I met Sketch in Val Royeaux, but he had spent so much of his life hiding among immigrants and smugglers he lacked the connection, resentment, and even accent of other city elves. His primary concerns were persecution as a mage, not an elf. He was not the bardic type, but I suppose the game was more forgiving than the templars.
I remember his books. Not unexpected for a mage, but most were mere distraction--the thinnest pulp of history. The only proper "mage tome" was a volume of Philosophy and Ethics Regarding the Manipulation of Summoned Creatures, which he owned because it was large. He was slowly covering every page with little preoccupied scribbles, as though the text wasn't even there.
