Hey. Ragnarok is the third chapter in Odin's journey. The fourth would be The Forgotten Sage. If you have finished Jotunheim from the base game, and your level is sufficient (200+), you can try it out. It has no bearing on the "main story" of the game, you just better play mythic chapters in order, that's it. Honestly, if you don't feel like it, you can entirely skip those ones, because it's a glitchy genetic memory of a simulation inside a mushroom position trans inside another simulation adventure. Or BS for short.
