MrsV has a familiar.
At our last apartment, we had two spirits who moved in (or were waiting) that we became aware of. One was a man who didn't do much beyond occasionally creep out MrsV and once giving me a serious case of the heebiddy-jeebidies when I was moving out the last of our stuff. The second was a Bakeneko
, who made herself known when we brought home our Egyptian Mau mix (her tail is freakish-long, which helped, I think). The cat (Lotus) isn't technically her familiar, but the Bakeneko will possess her often, and has helped us several times, especially when we were cleansing LilV's room before he was born to get it ready for him. She did most of the work, if I'm going to be honest.
Her tail recently split, so MrsV is very wary, and aware, of how rebellious she's becoming. According to MrsV, she tried to hide it for a while, but when she refused to help us on a minor energy sending for a friend who really needed it, MrsV called her out on it. We don't use her talents often, and occasionally LilV or I will spot her wandering the house.
