The Stone Guardians of the Lepisma Clan.
The Lepisma Clan is an Obelisk clan discovered underneath the Scarred Wasteland, at around the same time others of the same breed were discovered in Dragonhome. These Obelisk aren't to the same standards of those in Dragonhome, with most being "stuck" in their statue-like state and unable to become completely mobile. The Stone Guardians are a prime example of this-- but despite them seemingly being unable to move, they are among the most dangerous of the Clan, hence them being given the Guardian position.
These Guardians never leave their posts, given they don't need any form of food or water, and stand guard at every hour of the day. When members of the Lucilia attempted to approach these guards, most were injured upon reaching a certain radius, and unfortunately, one researcher who persisted ended up being fatally wounded. For those who spectated, there was no movement from the Guardians themselves and no traceable magic being put in use.
Having to abandon the deceased for their own safety, the Lucilia have stopped trying to directly interact with the Lepisma out of respect for their want to be left alone. Though, they still keep watch. It seems the Lepisma is all too aware of this, as the deceased's body was recently returned as a form of 'Warning' to the Lucilia researchers, months after the initial attempt at interaction. The body is still in the same state it had been left in, yet there are no traces of magic, or any other form of embalming, used on the body to preserve it.
