when she arrived at the Tavern someone through out a joke over her name.
That was fast death.
She is not a guest of the Tavern. She is...a part of a pact between the tavern owners and unknown demons from one far far demonic realm. Lords of that realm was bored a bit and they created a demonic weapon that have eyes that allows different demons to watch. Also they choose and orphan demoness and handled them to her. They ( lords) needed an interesting place with fights/interracial orgies/ unknown misteries/interesting beings.
And Lords found a place where all of it somewhere near - the Tavern.
They made a pact with the Tavern, and since then Jiz'goth stays close to the Tavern, patrolling the Hot Rift surroundings. She is always glad to travel with the Tavern visitors)
