He could, maybe, be something like that. Maybe lives in Dalygos but conducts business underground. Could be he's a businessman for a group, being one of those who goes underground to buy arcrystals and/or other things? I'm not sure I'm making sense
@Paarthurnax
In relation to your character, Aeteron in Mairgos slowly go mad being so cut off from the stars. That and his father *can* be a boss (or lieutenant as I'd prefer), but that's not the top position. There's five Underbosses that run Mairgos. One is Ruin, whose gang are the enforcers...
The sister cities were inspired by Piltover/Zaun from League/Arcane/Runeterra. But I haven't seen the show yet, waiting to watch it with someone so no spoilers please
