Created during the same era as the original Golem, the Sanctuary Sentinel emerged from the combined prayers and protective rituals of the ancient Jewish community's most devout scholars. It was bound to the sacred spaces through a complex series of Hebrew inscriptions and mystical ceremonies, becoming an eternal guardian of holy sites and sacred knowledge.

The Sentinel possesses the ability to create protective barriers of pure spiritual energy around sacred spaces and artifacts. It can sense threats to holy sites from great distances and communicate warnings to those worthy of receiving them. While powerful within consecrated grounds, its influence diminishes significantly in secular spaces.

The Sanctuary Sentinel serves as both protector of sacred sites and keeper of ancient wisdom, working closely with the Golem Guardians to preserve the community's heritage. It acts as a crucial ally in their mission to maintain the balance between the Golem's power and the safety of the region.
