Not spawned in the current version. It seems to me that she'll have her own side-branch in the dungeon in the future versions. She does minimal damage and the only dangerous thing she has is her poison. What makes her annoying is that she has 4k hitpoints and 40 endurance. That means that killing her is almost impossible as she regains hitpoints faster than you can take them away. <br>

She is said to be the child of Scabies. Kaethos the village elder has a line describing her, but it is not used in current version. It goes like this:

"Beware and avoid Lobh-Se at all costs! Fortunately, this is rather easy, as she only leaves her lair in the heart of the night and even then does not venture far, since nutrition is plenty there and she returns promptly when satiated."
