Rathwire Hillfort Stone

​Origin
Rathwire (Irish: Ráth Guaire, Fort of Guaire) is a village in County Westmeath, Ireland. According to legend this was built by the Chieftain Guaire who gave Rathwire its name. The ruins of the hillfort remain on the western end of the village. Legend has it that Guaire is buried in the ruins and is guarded by a savage dog who does not want the remains disturbed.

Effects
When someone holds or tosses the stone with the intent to summon the dog, it will either come from the stone in a wisp of dark smoke (in the case of the former), or appear from around the stone (in the case of the latter). Once summoned, the dog will savagely defend whoever it deems the "cheif" of the area. However, if pwoer is exchanged within said area, the dog will instantly switch alleigances to the other person.
