[Checkpoint] Drop down to the lower ledge and head to the other side. Go down the stairs and cross the walkway.

In the cut scene, Lara walks to the circular walkway ahead and spots Natla above. She throws an energy bolt to attrack her attention and orders her to shut the device down. Natla seems surprised that Lara made it through here, but it is a good chance so that Lara can see firsthand "the fruits of her labor".

Lara asks if this is the Midgard Serpent and Natla says "Of course not. Jörmungandr is the network of tectonic ridges that encircles the earth of the ocean floor." And she explains that when this relic unleashes its fury below, the very seams of the planet will burst. Natla then quotes the Eddas to Lara. "The Midgard Serpent will rise up and spew poison into the air, and all the world will be consumed by fire and ash."

Natla sets the device into motion and shouts "Ragnarök! The seventh age is upon us!" Natla knows that Lara is here to stop her, so she throws a fireball at her, but Lara manages to evade.

[Checkpoint] Area overview - You are standing on a walkway that surrounds the device that Natla set in motion earlier. The previous cut scene showed two angled supports, each one having a metal ring at the bottom. These supports supply with power the device and make it work. Your target in this area is to destroy the two angled supports and prevent Natla from using the device. In order to do that, you have to pull the metal rings in order to loose the supports free. However, the rings are hidden so you first have to reveal them by pushing two tall stone panels.

Middle level - You are standing on the middle level. You will first climb down to the lower one and push one of the two stone panels.

Making your way to the lower level - (The following sequence is shown in this page.) Facing the device, approach the egde of the walkway. Wait for one of the three floating platforms that move around the device to approach and jump to it. If you cannot do it from here, turn right and go to the other side of the walkway. Jump over the gap and approach the tower. At this point, a situational adrenaline begins. Natla flies from the left and throws a fireball at you, so jump away to avoid it. Then walk up to the edge of the extended part of the walkway and jump to grab one of the platforms.

Pull up and wait a bit as the platform circles around the device. Turn having the device to your back and wait for the platform to reach the ledge with the metal ring at the front. Use the Grapple to catch it and run off the platform to hang from the Grapple cable.

If you do not do that and jump to the ledge above the ring, a situational adrenaline will begin. Natla will fly opposite Lara and throw a fireball. Jump away to avoid it. Then wait for a platform to pass and jump on it. Wait if necessary until the platform circles around and reaches the ring. Use the Grapple to catch it and jump off the platform to hang from the Grapple cable.

Once hanging from the ring, turn to face the ledge below (the device should be behind Lara). Swing and jump to that ledge.

Lower level/ Pushing the first stone panel - (The following part until climbing back to the middle level is shown in this page.) Turn around and approach the edge. Jump to the ledge below and go to the right. Jump above the toxic water to land on the next ledge. Approach the left side of the ledge. This part is closer to the opposite walkway, so jump to grab it and pull up.

Be careful of the opening ahead! Walk around it, staying close to the edge. If you approach the edge where the walkway is broken, a situational adrenaline will begin. Natla will fly from above and throw a fireball at you. The camera does not help a lot and you may fall into the toxic pool as you try to jump away.

Go around the opening in the walkway and jump to the next ledge below. Go to the other side and jump to the next two ledges. Jump to grab the walkway ahead and pull up. Turn right and enter the alcove with the glowing symbol. Grab onto it and push the stone panel forward as much as you can.

The brief cut scene shows that this action reveals the metal ring on the back of the tower above.

[Checkpoint] Climbing back to the middle level - Stay inside the alcove and perform the Chimney Jump to grab the handhold on the left wall. Traverse to the left and jump up to grab the next two handholds above. Traverse to the left around the two corners and pull up on the rectangular ledge.

Back to the middle level/ Climbing up the tower to the upper level - (The entire process until pushing the second stone panel is shown in this page.) Turn having the device to your back. Jump to grab the handhold on the wall ahead, then jump up to grab the next one. Traverse to the left around the corner and jump up to grab the next handhold above. Jump to grab the handhold on the left and traverse around the corner. When you reach the end, jump up twice to grab the next two handholds. Jump to grab the handhold on the left hand wall and traverse left and around the corner. Jump to grab the handhold above and shimmy left. Jump up three times to grab the topmost handhold and traverse to the left and around the corner. Drop to the small square ledge below and turn left. Jump to grab the walkway ahead, shimmy left if necessary and pull up.

Pulling the first metal ring - Make a U turn to the right to find a square block at the back. Jump to grab the handhold and climb on the block. Climb up the two handholds and pull up on the ledge. Go to the back of the angled support and use the Grapple to catch the metal ring. Pull it to loose the support free.

The cut scene shows that this action breaks the support into pieces that are used as floating platforms that move around the device. The camera then shows Amanda entering the area and a Yeti thrall running after her. Just before dropping to the lower ledge, she kills it. As she tries to walk, two more thralls appear and she manages to kill them too. Natla notices her from above and throws a fireball, knocking her down. We then see more thralls entering the area.

[Checkpoint] Pushing the second stone panel - After the cut scene, climb down to the walkway and go to the other side. Take a look above to spot a metal ring on the ceiling. Use the Grapple to catch it and swing across. Continue to the other side where the second tower is. Enter the alcove with the glowing symbol. Grab onto it and push the stone panel forward as much as you can.

The brief cut scene shows that this action reveals the second metal ring on the back of the tower above.

[Checkpoint] Climbing to the L-shaped platform with the two low walls (even upwards) - (The following sequence is shown in this page.) Return back to the metal ring. Do not use it. Just take a look on the left to spot two white handholds on the wall. Jump to grab the first one, then the second handhold. Traverse around the three corners to the left to grab the handhold at the back of the wall. Jump to grab the next handhold on the left, then jump up to grab the handhold above. Traverse to the left and around the corner. Pull up and climb on the next ledge. Then climb on the L-shaped platform with the two low walls.

Approach the space between the two low walls. At this point, a situational adrenaline begins. Natla flies from above and throws a fireball at you. For the last time, jump away to avoid it. [Checkpoint]

Climbing up the device in order to pull the second metal ring - (This page shows the following sequence.) Walk up to the edge between the two low walls. When a platform passes in front of you, jump to it. Make sure you jump to the one that is closest to you! Facing the device, wait for a platform from the inner ones to approach and jump to it.

Now wait until the platform you are standing on circles around and passes beneath a series of handholds. When it does so, jump to grab the first set and climb up them. Jump straight up to grab the lowest of the second set of handholds and traverse to the left. Climb to the topmost handhold of the set and traverse to the right and around the corner. Jump up to grab the handhold that seems to be broken, then climb to the next one above. Traverse to the left around the corner and climb up the last three handholds.

Jump up to grab the handhold that goes around the device. Traverse to the right until you see the second angled support below you. Release to land onto it. You will start sliding down and end up in front of the second metal ring. Use the Grapple to catch it and pull it to loose the support free.

In the cut scene, the device starts to hover, since there is nothing to support it. Natla notices it and flies to the bottom where she uses her power in order to support the device. Lara realises what she is doing, so she throws Mjolnir towards her. The Hammer hits on Natla who falls into the toxic pool. Then the device collapses.

Lara runs away from the walkway and heads to the exit. She finds Amanda lying on the floor and tries to help her. However, Amanda is able to stand up and pushes Lara away.

"After killing the Midgard Serpent, Thor dies from its venom anyway." Amanda says tauntingly.

Lara replies "Not if you clear the corridor and get us out of here."

Amanda uses the Wraith Stone, but there is no power left. "Out of juice, just like Bolivia. The good news is we saved the world," Amanda says while Lara is trying to figure a way out, and continues "The bad news is we're going to die here, just like your mother".

Lara did not like what she heard and turns around to punch Amanda, but she stops. Apparently, "Bolivia" gave Lara an idea. She locates a dais, same as the one in Bolivia where she last fought with Amanda. She runs to it and Amanda follows her. And yes! There is a sword stuck in a stone like in Bolivia. Lara figures that her mother must have tried to use it to escape but did not know how. Lara, however, knows how it works, so she presses the sword into the stone and a big metal circle rises up.

Although the symbols on the stones glow, the portal does not work and Lara wonders "If pulling out these artifacts always brings you here, what will happen if I'm already here?"

Amanda replies "Maybe you'll go to hell."

Lara then spots a piece that is missing from one of the stones, so she puts it into place. But she cannot hold the stone and reach the sword at the same time, so she asks Amanda to do it.

"What about you" Amanda asks. Lara replies that she can reach her if Amanda holds out her hand.

"You trust me?" Amanda asks.

"We're out of time, Amanda".

Amanda thinks about it and she finally makes her decision. She pulls out the sword and yells "Now!" while at the same time reaches Lara's hand. The Looking Glass is now activated.

The camera shifts to another room with a same dais. (If you have played Legend, you should recognise this room. It is where Lara found the Excalibur in the Monastery of Nepal.) The symbols on the stones glow and a big metal ring rises up. In a few seconds, both women tumble out. Lara stands up and picks up the sword.

"So, it's back to this, is it?" Lara asks.

"What, you think we're even?" Amanda replies.

"Would killing me make us even?" Lara asks.

Amanda thinks about it for a while, but she decides to leave. Lara approaches the broken pedestal and picks up two pieces of paper with Yeti drawings. (Again, if you have played Legend, you should remember these drawings from Lara's journal.)

"Goodbye, Mother. Rest in peace."

Lara leaves shows the dais.
