Every non essential character died two of them in the very last section inside the castle. The encounters were ridiculous with 4-5 xivilai along with their clanfears, a storm attronach, spider deadra and Daedroths all of them at once!!! I swear i had a moment that my high end machine couldn't handle the sheer amount of creatures and npc's chaos that was happening at the same time. Was that part of the plan or is something bugged in my game?
I'm playing in the default difficulty with a level 32 spellsword, developed naturally without any form of efficient leveling and the whole game up until now was smooth and easy. No mods except UOP
