Two millenniums ago, I sacrificed my body to strip Chaos of his power and seal him away within Master Emerald with my own spirit.

My spirit coexisted inside the Master Emerald with Chaos, until it was shattered by Dr. Robotnik, which released me and Chaos. Now I'm in a spiritual form, free to roam around and help others again, including you. Please, call me Tikal. Apologies for my long introduction.
