Tankenka's Mirror

Tankenka's Mirror was a normal mirror wich was awakened by a fragment of a water kami fused within the body of Tankenka, a former member of the Order of Courageous Reflection at the monastery Yaruki Jukko.

Preamble
The Order believed that meditating before a reflective surface was the only true path to self-enlightenment. When the monastery was wiped out during the Battle of the Humble Turtle, the shinpu of the temple, Tankenka, took it.

Awakened
Tankenka had had a fragment of Shanshien, a water kami within him. It was enough to awaken the mirror, which became a nemuranai, bonding to Tankenka.

Abilities
The mirror was able to attune to an owner after a certain time, gaining a supernatural link with him. Its carrier could not be affected by water spells or effects, nor could he drown. If he was ever part with the mirror, its surface would reflect his present location whenever anyone else looked into it.
