A person on whom Fae magic doesn’t work, capable of seeing past the illusions or “glamour” cast by Fae to the true nature that lies beneath. Some can also see Tabh’rs, hidden portals between realms. Others can sense Seelie and Unseelie objects of power. Each sidhe-seer is different, with varying degrees of resistance to the Fae. Some are limited; some are advanced, with multiple “special powers.” For thousands of years, the sidhe-seers protected humans from the Fae that slipped through on pagan feast days when the veils grew thin, to run the Wild Hunt and prey on humans.
