House Phiarlan is a dragonmarked house known throughout Khorvaire, although they are now based in Sharn, Breland, after their former base of operation in Cyre was destroyed in the Mourning. To the public, Phiarlan is a house of entertainment composed of bards, actors, artists, and acrobats, though in secret it is a house of spies.
While all members of House Phiarlan are elves, not all members carry the Mark of Shadow dragonmark. House Phiarlan includes 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 were destroyed in Cyre, and they have not created a new headquarters, preferring to stick to the shadows.
