The Dead Lands of Athas
Every templar receives a sigil that is the sign of their rank and station as a templar within their city’s templarate. The form of the sigil is unique to each city‐state, but is always unmistakable for what it is. The bulk of such medallions are crafted from glazed ceramic, but higher-rank templar sigils can be carved from precious stone or cast in silver, gold, or even steel. The sigil serves as your divine focus, and allows a templar to facilitate the will of their Sorcerer-Monarch through spellcraft.
Invoking a sigil creates a brief connection with the user and the Sorcerer-Monarch to which it is bound, and their ruler can choose to deny the spell if they so choose (though this rarely ever happens, unless the templar is attempting to do something the sorcerer monarch is greatly opposed to). Woe betide the poor should who might attempt to use a stranger’s sigil, or a renegade templar attempting to use their sigil one last time. Such individuals usually end up as a pile of greasy cinders.
