Loyal servant to Doplin? Don't make her laugh. Velna has always served her own desires, and such desires coincide with that which her true loyalty lies... Avalon. With her Origin of Time, Vestra, she strives for the creation of the world in which only Mystics survive.

In the DL? Not much different. Possessing magical immunity and being able to summon a physically-immune attacker is fairly hot stuff, and the tag-team combination her and Vestra pull together is devastating if the enemy is prepared... which they rarely are.
