Sigil of Yog-Thul
The Sigil of Yog-Thul is 2 dragons intertwined in a fight, though when you look close, their a head on the end of the tail and it is actually biting itself. It’s claw rend itself, and teeth tear chucks of flesh out. It appears to move slightly if you stare at it long enough or move it through different angles. The eyes of the face of the dragons seem to stare back at you as you look at it. The great sigil was consecrated to Yog-Thul to channel his power to those who would venerate him. The Sigil of Yog-Thul is his fetish of power on Helca itself; He beomes significantly weaker if his sigil is borken or corrupted.
