What do you think the role of Angels would be, and are they limited to only Hope players? Eridan's planet was full of them, but we never learn what sort of role they have to play as he embarks on a genicidal quest to destroy them all. And Jake only manifests them under control of Aranea. I want to make a fan-planet with Angels.

Angels are definitely Hope-coded, sadly though I am not sure we even have enough context about them to know what their Role may be because as I’ve mentioned in the past, they seem sort of like Hope Elementals, and as far as I can tell, we don’t see Elementals of any other Aspect within the comic. I could be wrong though, and this is a thing I would love exploring more of. Chances are your Fan Planet will have to be Hope-Coded, unless you had like, a Land with all the Aspects and just elementals of each of them.
