Blood Sage

Introduction
[Lost Girl] Very little is known about the Blood Sage except that it is a very old type of Fae. Trick is the only known Blood Sage in the show, possessing the title of Blood King (Although it is unclear whether this is a specific title or merely something he received as the only Blood Sage left). However, his daughter and granddaughter have inherited some of his blood magic. [Lost Girl]

Powers and Abilities
[Lost Girl] Anything he writes in his own blood comes to pass, but it will only come at a cost, and a terrible one at that; when Trick wrote a means of ending the war between Light Fae and Dark Fae, it resulted in his own daughter, Aife, becoming a violent terrorist determined to disrupt the peace. However, when he wrote to ensure that Bo would defeat her mother, the downside to this happening of his blood magic is arguable. It is unknown whether when Dyson made a deal with theNorn to give Bo his strength at the cost of his love for her was a direct cost of Trick writing in his own blood, or if the consequence was the awakening of the Garuda who had been sleeping since he was starved by the time Trick wrote in his blood to end the Great Fae War.

According to Trick, his powers only work when he writes in his blood of his own free will rather than being forced, although given the circumstances under which he revealed this information he may have been lying. It is very likely that Trick needs to write down every detail of what he wants to occur or else it might be interpreted into some other way, since he was responsible for writing down the laws that govern both Light and Dark.

Trick cuts his left hand, puts blood into a vial and uses it as ink to write runic inscription.

In the episode 1.13 Blood Lines while Trick writes, the unfinished rune Mannaz (the right vertical line is not written yet) appears on Aife's forehead and she lets go of Bo's hand, thus sacrificing herself for her daughter. [Lost Girl]
