RIP to him.
I really liked him. There are minor characters in the dragon age series I absolutely love.
aside from him the guy in the bar where you get liliana "I'm NOT THE BLIND ONE!!11!1!!1"
and the Hermit are amazing. "Gimmie that"
I love Tapster's Assemblyman.
I wish I could make him King.
Amusingly, despite the comparisons to Christianity, Andrastrianism could be a big issue in the Dwarven Empire due to the way Islam worked out in India. The caste system was a pretty big deal way-back-when and Islam came with the statement, "everyone is equal under God." As you can guess, this kind of was, a "nothing to lose, everything to gain" sort of situation for the Casteless.
I could see something similar happening with Brother Burkel.
