Vakrick comes from a long name of forest dwarves. Ones he drink so much of dwarven wine that he was banished from his home village. Since then he never touched alcohol (in large numbers).
As a result of this he doesn't want to talk about his past. Vakrick, as mentioned, has almost no friends. He seeks out the place to live so he travels a lot. Thats why Greencloak has had little interaction with races outside of Dwarves and the occasional forest elves and humans. Because of this, he is a real adventurer.
He is religious. As a forest dwarf he follows the Druidic deities known as the Aspects as the two silver rings of Anbella. He’s a real master in brewing.
