"Jolistina Superio, elf and aspiring undead." she smirks and laughs as she mentions this "Oh? Well Rolthy sent me here to kill several of the rich bastards who were scheduled to attend the party here, but everyone else were just bonus points!" she again giggles as she says this. "I dressed up and snuck in here, shooting my disease infected bolts at the bastards, watching them run and scream, oh it was so fun! Rolthy's new employer wanted them dead, but I don't know who or why, before you ask, silly rabbit."
At the question about where Rolth is she tilts her hear.
"Rolthy has been pushed around by this new employer. He, or she..." she grits her teeth as the possibility of it being a woman unfuriates her "Has kept him locked up in the some hidden laboratory in the city. Keeping him locked up my poor Rolthy has barely been able to speak to me, so I stole one of his spell books to keep for a keepsake after he came and visited me the day after everyone died."
"Ocarina?" she seems confused into you explain it to her "Oh! The handsome Varisian with the weird wind instrument! Rolthy was so happy when I gave him the wrapped up Varisian to experiment on. He was so happy we got to use the main bedroom and he gave me two scrolls of animate dead, which I used to make this beautiful display" she seems really happy when talking about Rolth in this light, but then the smile fades "He had to leave as he had two women with him. They were heavily armoured and carried the young man off to somewhere. These woman had red-plumed helms" You recognise these helms and description as being that of the Gray Maidens.
