You’ll have to talk to Julienne Fanis in Arcane University for some more detail on their location.
She’ll tell you to find a book called Knightfall.
It can be bought in The First Edition in Market District.
After reading the book, a new map marker will be added.
Go to Frostfire Cave.
Use enchanted door (screenshot above) and you’ll find yourself in Garridan’s chamber.
There’s a Frost Atronach here, together with 5 barely visible crystals.
Use the map below to find them.
Be quick about it, as the frost in this room impacts your health.
Go back to S’drassa to get your reward.
Go there and break in.
Inside you’ll meet Rosentia herself and a few scamps.
Talk to Rosentia to find out that these creatures are here because of cursed staff she recently bought.
Go to Alves Uvenim in local Mages Guild.
Agree to that and go to Darkfathom Cave east of the city.
The cave is a small dungeon filled with daedric monsters.
When you reach the altar in the eastern part of the map, drop the staff and leave.
You’ll get Ring of Eidolon’s Edge as your reward from Rosentia.
HINT: When you possess the staff, Everscamps that follow you are good training assistants.
Just practice your battle skills on them if you like.
Talk to the Count about her, he’ll ask you to try and solve the problem.
Talk to Mazoga herself to find out she wants to speak to Weebam-Na.
Find him in Leyawiin and escort to the castle.
You might have to raise his disposition in order for him to agree.
Tell her that you will accompany her and do so.
Once you’re in there, Mazoga will start a conversation with some bandits.
Assist her when the fight breaks out.
When they’re all dead, go back to the Count.
Mazoga knows that he’s hiding in Telepe, west of Leyawiin.
Ruins are not well guarded, apart from Brugo there will be some low-level bandits.
The grateful Count will grant a knight title to both you and Mazoga.
He’ll tell you to go to Greyland and kill Kylius Lonavo.
Easy as it gets - just enter the house and do your thing.
Nobody will bother you with any alternative solutions to this quest.
Take the ring from Kylius body and show it to Lerexus for some gold.
