Character's talisman.

Metalingus usually wear(s) this talisman when they go(goes) somewhere far from home. This rock can be used for searching other magical items, persons/characters/people around and for teleportation (teleportation radius is not more than 10 meters further/higher).

The talisman looks like a half-flat round rock with a fire/air/magic symbol on its front side. It's not that big.

A brief story:

Metalingus found that strange rock when they were(was) on a trip to dark woods. They got in mind that it may have magic abilities, so Metal took it home and then started using as a special magic instrument.
