Sidenote: I'm actually confused as to what Isevel's aura/blood colour was supposed to be so I just went off of what was on her infobox template; was it supposed to be one of the other colours

I believe that the Princes of Hell were all supposed to be themed after fire-related things. Lucifer is Matches, Mammon is Burning Money, Asmodeus is Cigarettes, Satan is Auto-da-fe, Beelzebub is Cannabis, Leviathan is Wildfire, and Belphegor is Bonfire. Though, I'm assuming any exception can be made at LAT's wish

The other suggestions are good, perhaps with Mercuron B and G being an exception, if LAT already has ideas for them

Maybe we can have Thristel-Immo's aura somehow connect to the Big Grey Box Snake
