House Phiarlan across the face of Eberron. While all members of House Phiarlan are elves, not all members carry the dragonmarked Mark of Shadow. House Phiarlan contains both the Entertainers Guild and the Artisans Guild, but they also secretly run the Serpentine Table and the Carnival of Shadows. During the Shadow Schism, a portion of House Phiarlan splintered off to form House Thuranni. House Phiarlan's original headquarters was destroyed in Cyre, and they have not created a new headquarters, preferring to stick to the shadows.
