The Nightmare War
Vaslo is the elderly and somewhat senile uncle of Drakeus. It is rumored that he was one of the original creators of the warforged; it is also rumored that he would be the Head of House Cannith were it not for the regrettable state of his wits. Vaslo has recently been seen in the company of his (rumored) young lover, a stunning lady with lavender hair. They have just embarked on a lover's cruise to Xen'drik, to tour the sites Vaslo visited in his youth.
At the conclusion of Season 1, Vaslo is restored to his full mental capabilities, and proves to be a very capable individual indeed.
