Strengths
-- Unconventional -- in part owing to his difficulty with learning spells the "usual" way and in part owing to his strange way of thinking about magic, Myr makes unusual uses of his spells fairly routinely. Creation already lends itself to lots of out-of-combat utility; he's just expanding on that.

-- Confident -- even if he's faking that he knows what he's doing, he's faking it very convincingly.

-- Persistent

Neutral
-- Fearless -- with a couple of exceptions (see below), he's simply...not afraid of things or the possibility of harm coming to him. He has been doing well enough so far at navigating the world that he's not afraid to try things that are, probably, not very safe for a blind mage to do on his own--or dare others into doing things with him that could get him hurt. This can also get him in trouble as a loyalist, since he will not shy away from or demur about his beliefs if it comes to a direct challenge of them.

Weaknesses
-- Entropy magic -- has a spot of the ol' PTSD when it comes to this. What's worse is he won't acknowledge it, won't talk about it, and won't try to avoid the possibility of being fielded with an entropy mage because he thinks he can handle it right up until something's cast in his general vicinity and he panics.

-- Learns by doing/doesn't test well -- you can tell Myr over and over again how to do something, but until you show him how to do it, he'll have Maferath's own time picking it up. This meant he advanced more slowly than his peers through the Circle until he hit upon ways to learn and remember that worked for him (mostly writing things down and coming up with gestural components better matched to their spells).

-- Trusting

-- Naive

Quirks:

-- Can't whistle--don't even bother trying to teach him he just can't.

-- Habitually forgets Dalish words but remembers the translations just fine.
