Magnus’s RPG empire on the portal.

I quickly grabbed the altar.

Alright, let's get going. The Rune Priest and you head out, but not upwards, instead downwards. Sorry, but at the entrance, they will most likely take the altar. We'll hide in the cave. You're already heading towards the lava; it's getting hot. The lava is bubbling. Let's go.
You enter the cave. You walk and enter a hall; everything is here, including food, scrolls, and books. Stay here. The entrance is guarded by lava dragons.
