We take the raft toward the Viking battleground. On the way Tom senses that we might be being watched by something, but nothing appears.

Thinking about what motivate the vikings to help us defeat the guardian of the volcano, Slate mentions that in Norse mythology there is a giant serpent, Jormungundar, who is Thor’s arch-enemy. Thor defeated him and walked 10 steps before dying himself, from the serpent’s venom. If we mention that this is the world-serpent, they may help us in our effort to kill the beast.

We come to the battleground and see weapons, armor and skeletons lying about. Slate notices a huge skeleton sticking out of the ground, it looks like a large serpent or dinosaur.

Gabriel finds armor, a helmet and two maces in the rubble and starts to descend into the crater. As he does this, some of the spectral viking warriors start swirling towards him. The giants, ogres and trolls do not seem to care about him. He sees something towards the center of the crater and climbs over the rubble to get it.

Finally getting to the bottom, he sees that the shiny object is a weapon — a hammer. He tries as hard as he can, but can’t lift it. Slate thinks that this may be Thor’s hammer, and it’s possible that we may not be able to lift it because according to myth, only Thor could do so.

We all head down into the crater to check it out. Whitmore reads the runes on the hammer and it indeed says “Mjolnir”, which is the name of Thor’s hammer. Whitmore is able to translate to the Vikings. We ask them for their help in defeating Jormungundar, but they say that he has already been defeated. We attempt to explain that we have all been trapped here and they think that this is in fact Valhalla, so are disinclined to try and leave.

Whitmore suggests that we try and talk to the spectral Thor, who is very prideful — we may be able to exploit his character flaw. He coaches Gabriel, who then approaches Thor and says that he is a weak fool (in Norse).

Thor hurls the hammer at his head and Gabriel narrowly dodges. Thor asks him why he thinks he is so easily defeated, and Gabriel says that if he had a hammer like Thor’s he could defeat him. Thor obliges, gesturing, and the physical hammer floats towards Gabriel and he finds that he can lift and use it. He moves to attack Thor, and they fight it out for several moments. Gabriel strikes and actually knocks Thor off of his feet. He starts pounding on Thor as he is flat on his back, and Thor pushes him off with little effort. He asks how he was defeated by a mere mortal.

We change the subject and ask him if he will help us defeat the fire serpent to free us from here. He agrees, but he says that the Atlanteans must help us in our task so we will all fight for our freedom. He gives Gabriel a less powerful version of his hammer to use in the battle. We go to the Atlantean city and talk to them, and they decide to join us. We all journey to the volcano and ascend to a cave, and sure enough we find the lair of a giant red tyranosaur and some of his dinosaur friends. His eyes glow as if they are on fire.

Goodwin hits the T-rex severely with his flying machete, and then Slate and Whitmore take shots with their firearms unsuccessfully. Gabriel flings his hammer at him and slams him for more damage. After quite a long battle, Gabriel slams him with the hammer and a jet of flame courses out of it, narrowly missing him. There is a white light and everything disappears.

We wake up on a beach, and we see pillars like we saw when we first arrived to Atlantis. We also see our zeppelin in the distance. Professor Westmore is waiting near the zeppelin and he has food for us.

The cat people and Atlanteans are here. The Norsemen are here, but they are being picked up by valkyries and carried away. The t-rex that we defeated is here, dead, but we hear other dinosaurs in the distance.

Westmore tells us that we have been gone a while, and he heard that an island popped up in the middle of nowhere so he thought that he would check it out. He shows us a newspaper and it says May, 1944…which is 8 years after we left! There is a war in Europe, and it is not going well for the Allies. He suggests that we discuss what to do.
