Ah but he isnt closedminded and pre-determined, he recognises your worth eventually and makes you an honorary Telvanni.
You get a bedroll and chest and everything.
My Telvanni Nerevarine would approve.
I laughed hardly!

A bedroll, wow.

But seriously, I love the guy. I look forward to join House Telvanni once again.
It's funny, he was one of the Mage Lords I had no great feelings for in Morrowind. At first I was disappointed it's not Divayth Fyr on Solstheim, but everyone loves him, anyways. Bethesda chose very wisely. They let a less prominent Telvanni Master become one of the greatest Skyrim characters.
