Yorick and Evelynn.
They didn't have their lores updated, which means that they could have ulterior motives towards the Shadow Isles Coven.
Evelynn may even oppose the order and is assassinating the people that support the Coven in order to give her power to reign over the Shadow Isles herself. She may even work for an unknown character who gives her orders that she carries out. She may even agree with the order, but wants to be independent and has her own agenda to work.
Yorick may want to get something out from all the chaos. He may need bodies for some necromancer ritual. He may just go on with his business like he did before. He may want to play apart in the story because the order had something to do with his family.
Idk. just me thinking.
could actually be against the Shadow Isles. Something along the likes of her being prophesied to help the Isles and her response is, "Nahh..."
