Haer'Dalis

Haer'Dalis is a tiefling actor and planewalker, and a member of the planar faction known as the Doomguard. He doesn't live anywhere permanently, but most frequently returns to Sigil. He belonged to Raelis Shai's theatre troupe at one point, and at least at that time, in 1369 DR, stayed on Toril for some time.
