Priscilla

A female goblin NPC you can meet while exploring(I met her when I was level 26 and she was 32) she gives you the option to talk, sex or fight, presumably low corruption is needed(I had 31). Winning a fight causes a regular goblin defeat scene. Talking to her causes her to tell you she's looking for a mate that isn't very corrupted. Chosing sex makes a new sex scene that isn't in the regular female goblin defeat scene.

After unlocking Soul Sense, and visiting her enough times, Priscilla can be found using Soul Sense in the Soulforce tab in Camp. This doesn't remove her from encounters as she is on the Goblin encounter table.
