Well, if they would figure out an actual theme to stick with, and explain their thoughts & people would be ok with it, then Sven made his own choice of his attire. If they literally set the entire story ablaze, then he still made his choice for his own attire.
But it was HIS CHOICE! lol
Anyway, I don't think it is too far-fetched to go with something of the bride storyline that I thought it was, which is directly from DnD, for a choice of an ascendent vampire. Otherwise, something with substance instead of a cheap one-trick BS story that invalidates the entire reason he was the face that brought many to the game—only one trick evil or one trick good. Nothing in between, that is just........ugh...........boring. And it's a complete throwaway for the entire character.
