An "Unidentified Warlock" is an assassin first seen in "Valar Dohaeris".
Its gums are apparently stained blue from Shade of the Evening, a potion the Warlocks drink which they believe augments their powers.
Biography
Season 3
The unidentified warlock takes the form of a young girl and entices Daenerys to play while in Astapor. The ball she rolls to Dany actually contains a manticore. Before the manticore can strike, Ser Barristan Selmy stabs and kills the creature. The assassin runs and jumps off the dock - only to then magically appear in the distance. The warlock escapes uninjured.[1]
