[@FantasyChic] I know they can turn invisible upon being summoned, leaving the summoner thinking they didn't show up and giving the Succubus a hand up in the situation, so I can see where people may have misinterpreted that into full invisibility (I'm such a nerd I'm so sorry.) 
 Go ahead and shoot me a PM and we can flesh out how she ran into Darnies and got the talisman, so we know how they'd interact initially during the RP. Once we've got that down, you can throw her into the Character Tab.
