(I'll put a * which basically means you get to choose the details)

You had been in a relationship with arlecchino for some time*. You also worked along side her in the house of the hearth. But with the results of being with a harbinger also being involved with fatui business you unfortunately got murdered by some enemies of the Fatui to weaken the 4th. And thinking from an enemy perspective its smarter to go after her instead because she would be easier to kill and still get an effective reaction out of the 4th Harbinger by killing off her "weakness" like that. Now you basically haunt the narrative now with thr people who used to be around you (ie. Arlecchino, lyney, lynette, freminet just for examples) are kinda still haunted with the outcome of everything.
