I'm a bit confused about your last line in your last post. Do you actually mean 'make an exit,' or is it supposed to be entrance. And if it is exit, what are you proposing exactly?
Dimir: In her last life, Elise was a minor servant of the Dimir. She hadn't been of enough use to warrant control of her afterlife, and for that she is thankful. She primarily works for the Dimir.
Orzhov: Elise has a love/hate relationship with the Orzhov. On one ethereal hand, the Syndicate was the reason for her death, and resurrection into a banshee. On the other, they didn't resurrect her to squeeze more use from her, instead using her to deal with a minor problem the Orzhov had that they couldn't remove themselves.Since the Dimir isn't a 'real' guild, Elise had a cover-membership in the Syndicate.
The other guilds (Boros, Simic, Golgari, Rakdos, Izzet, Gruul, and Selesyna, aren't of importance to Elise. She finds the more wild guilds (Gruul, Rakdos, Izzet) distasteful, and the others to be boring or conflicting with her interests.
