ulvelsa is v different from vai-shei

they both join the dark brotherhood but for different purposes

vai-shei joins it so he can be a (unofficial) shadowscale!! hes into the tradition and the tenets and stuff so its new way of order is a surprise to him!!! he doesnt agree w it but what can he do. astrid is in charge so he just goes along with it but he has a bad feeling that somethign bad is gonna happen (AND IT DID!!!!!!!) once cicero comes with the night mother he feels like things are gonna be how they are meant to be!! andd then hes named the listener!!!!! when it comes to the decision of whether he would kill cicero or not he wouldnt. he would follow the tenets!!!!! (I KILLED HIM IN MY GAME THOUGH OOPS) i think over time vai-shei would restore THE TRADITIONAL DARK BROTHERHOOD WAYS!!!!!! and form the black hand again with nazir and babette

ulvelsa on the other hand doesnt really join the dakr brotherhood for any of that. she joins because she gets to kill people. she wants to cause as much havoc as she can in skyrim!! LAND OF NORDS MUST GO DOWN!!!!!! she’ll be esp pleased at that one contract where you have to kill the emperors cousin at her wedding or w/e. ulvelsa doesnt rly give a shit about the dark broterhood she just exploits them to kill people and also get paid for it hehhhhhh even though shes named listener she doesnt want the responsibility so when they move to dawnstar sanctuary she just BAILS OUT and goes to the thieves guild
