Figurine of wondrous power

A figurine of wondrous power is a small statuette ranging in size from a grown man's hand to the size of a little finger, that is relatively similar in shape to the extra-planar creature that it turns into. These rare items transform into many types of bestial planar creatures that understand common and follow the orders of the wielder of the statuette. These creatures are called by the name given to the creature upon the item's creation. They cannot reside on the prime material plane for large amounts of time and therefore are bound by the figurines to return to their home planes to rest after a set amount of time on the prime. If the creature is slain while on this plane it will revert back to statuette form and live on, but if the statuette is destroyed the item becomes worthless and loses all enchantment. Depending on the strength of the enchantment this artifact's effects should be permanent unless passed through an anti-magic field, which could disrupt the base structure of any magic item.

Guenhwyvar
Guenhwyvar is a unique figurine in that the statuette summons it's creature rather than transforms into it. This could be due to the strange circumstances of its creation and the uniqueness of the beast, a particularly intelligent and powerful panther. It can be summoned by calling her name from her black onyx figurine, for up to twelve hours of every 48-hour period. Although it is possible for it to be summoned for longer than that or before the cycle of 48 hours begins again, it is very draining and probably unwise to do so. Guenhwyvar also has the power to transport any creature touching it to it's astral home or to the Ethereal Plane.
