Casser-Bok

Casser-Bok was a Vahnatai Crystal Soul who lived in exile after being banished by his people, in a lair in the region that humans name the Za-Khazi Run. He claimed to have been a powerful warlord in life.

Eventually, he tasked several Avernite adventurers with relaying his request to be allowed to return from exile. This was denied by the Vahnatai, who declared his crimes were too great.
