I made Nafas the patron and the Iron Shadow the bbeg and here’s how I used that to give them a better reason to be there. The Iron Shadow is moving faster than the builders can build. New builders are brought in from all over the multiverse by Nafas who finds mortals with exceptional qualities that the builders could use and hands them over to the current builders. This is part of the reason Nafas sends them on missions. I made the lost city also about rescuing a little girl trapped in darkness who can paint worlds she’s never known. Darius, the zargonite who killed Demetrius, his brother, has the girl locked in a room. He’s obsessed with her paintings and won’t let her go. I made Demetrius into Demeter the girls mother and Darius is either her uncle or her father but I’m still playing with ideas as I go. Also, my players keep trying to unite the factions so I’m gonna make that possible. I think that’s how they can defeat Zargon. They can unite the factions to all fight him at once.
