The Wheel Turns

Question: So what's next for your PCs now that they are all gods?

Oh, you know. Saving the world, staging political upsets, getting married, Ragnarok. The usual stuff Scions do.

Getting to Legend 9, while an exciting achievement that unlocks a lot of doors in the Overworld for them and makes them feel very fancy indeed, is not like winning the game. Being Legend 9 still leaves them very much less powerful and well-known than most of their pantheons, and the problem of the Titan war hasn't gone away (in fact, for most of them it's worse now, as they're just powerful enough to get thrown at Titans as cannon fodder). They've all made enemies along their paths to godhood, meaning that there are plenty of plans and disasters chasing them down, and they all have goals of their own as well. Divine politics is a nightmare they're only beginning to experience (and realize that they can't possibly handle yet). The Norse PCs, in particular, are now fully part of the general Aesir hysteria over Ragnarok, the Loa PCs are dealing with a concerted attempt by their pantheon to return to their roots in Africa, the Aztec PCs are in an uproar over former allies attacking them during the full-on war they're currently having with Tamoanchan, and the Greek PCs can't set foot outside their houses without getting into a fight with disenfranchised Greek Titans, pissed off Greek gods, or each other.

In short, the same things they were always doing, but more so.
