Loki TemnaDemon Alias:
It allows the use to switch the sense receptors of each of the senses, thus when you go to see you are actually smelling. It is done by touching the person with a thin blue line of chakra. This thin blue line is hard to see even with eyes that can see chakra as its thickness is less than the lead of a pencil. When the thread comes into contact with someone it switches the senses.History/Bio:
Yggdrasil has been an ancient secret of the Temna clan, it has been said that it refuses to help out when sealed in another type of ninja. However we need to speak about how it came to rest in Loki, it was soon after his host had died and the elders of the clan converged with Yggdrasil. Over the next couple weeks they went over the younglings and decided upon a child who had just been born to two high ranking assassins. This child was of course Loki, and the sealing process gave him many many scars.
Ever since he could remember Loki has Yggdrasil inside himself hiding the secret from everyone but the elders of his clan. For this fact he slowly ostracized himself from his clan and village which pushed him into becoming a wanderer. Yggdrasil enjoys being a sadistic asshole and constantly bickers with Loki, however he has claimed that Loki has become his favorite host.
