Zhar is a Great Old One and appears as a colossal mass of tentacles. The being came from the star Arcturus, but now dwells beneath the buried city of Alaozar on the Plateau of Sung. It is served by a cult known as the Tcho-Tcho's "Brotherhood of the Star Treader." When called upon by the proper incantations, Zhar can project itself astrally in the form of the Tulku. It can also telepathically transmit its urges to its worshippers. Zhar is believed to be physically connected to its "twin", Lloigor, perhaps by a long extension of tentacles.
