Virtrium

Virtrium LLC was founded in 2006 in Phoenix to build MMO technology and products. In 2007 it acquired the assets of Tulga Games, including Horizons: Empire of Istaria — originally launched by Artifact Entertainment in December 2003 — renamed it Istaria: Chronicles of the Gifted in 2008, and has kept one of the earliest playable-dragon MMOs running ever since as a small studio.
