Previous assistant to Isaac Dragonblood
Abraham Axedigger was the assistant to Isaac Dragonblood when Isaac was still alive.
Isaac’s death hit Abraham very hard, and Abraham wants nothing more than to seek vengeance against those he deems responsible for the matter.
Shortly before Isaac’s death, Isaac cut off most of Abraham’s beard for perceived insubordination. This is of course an enormous dishonor among Dwarves and it haunts Abraham at night that this was one of his last interactions with he beloved leader.
