Lake Marvel is one of the oldest lakes on the planet. It is the body of water from which the Madrid River flows. In it's center lies Marvel Island. Mostly a flat island, the island provided a site for the Capital of the Gainese state, California.
The lake was believed to have formed some 250 million years ago when the Espana peninsula which was once an island, collided with the Super Continent of Tellawow Island. From the collision it is believed that a body of water now known as lake Marvel was formed.
This Lake is believed to be the site were the Goddess Trakaska, Tellawowian Goddess of the Seas, was born. Her story is widely regarded as to why the lake first came to be.
