I’ve played a lot of Grim Dawn, FF is no different. I think it would be awesome to see a crossover between them
I’ve only got about 70 hours on FF, but I feel this could be something that happens very late, even after the larger raider attacks. Featuring both the aesthetics and creatures of the Aetherials and Chthonians (or any creature).
Some special decorations or rewards inspired by Cairn would be awesome too lol
