The Quetzalcoatl tablet is a stone carving depicting the god, Quetzalcoatl, which was placed at the top of the Earthbound Immortal Shrine. Greiger, Annie and Max built it in worship of Quetzalcoatl to protect the shrine. During Jack's Duel with the Familiar, the Familiar got annoyed after Jack took the upper hand and tried to kill Jack by making the ceiling collapse above him. However the tablet lit up and emitted a ray of light. The Crimson Dragon then appeared to protect Jack, Yusei, Greiger and Max.
