Once the cult of Turms Termax became the de facto power behind -- and, eventually, on -- the Thulian throne, its hierophants took on roles of importance throughout the empire, acting as advisers to provincial governors, military leaders, and even the clerics of the state-sanctioned Great Church. Each of these hierophants brought with him a peculiar magical device known to later generations as a brazen head.
As its name suggests, a brazen head is a brass representation of a man's head (that of Turms himself, according to some sources). However, the head is enchanted and possesses two unique functions. Firstly, once every three days, its user may commune with Turms Termax (as per the 5th-level cleric spell of the same name), with the god's answers issuing from the mouth of the head. Secondly, its user can, if the proper command words are known, communicate by speech with the user of any other brazen head within 5 miles of his current location.
Brazen heads were never produced in large numbers, but, over the centuries, enough were crafted that they can still be found in Thulian ruins everywhere. Likewise, many magic-users (not to mention groups like the Argent Twilight) seek out brazen heads, using them as a means to gain access to the secret wisdom of Turms. Others seek out the heads to destroy them, believing them to be a tool by which the god of magic -- or his contemporary cult -- seeks to spread his influence throughout the world. Indeed, there are many who claim that brazen heads only selectively tell the truth, so as to seduce their users into the unwitting service of the Thrice-Great. There are similar claims that continued use of a brazen head leads to religious mania, with the user forsaking all other deities in favor of Turms.
True or not, there are many superstitions about brazen heads and the mere mention of them is enough to frighten some who fear and revile Termax and his once-mighty cult.
