Babi Lighthouse

Babi Lighthouse is a building project started by Babi, the ruler of Tolbi. In his youth, Babi had visited Lemuria with his companion Lunpa, and while there he had gathered a stock of the Mystic Draught, Lemurian water that slowed down the aging process. When Isaac and friends met Babi, his stock of the draught was running low. He had ordered Babi Lighthouse to be built in order to guide his ships through the fog of the Sea of Time so that more draught could be obtained. This lighthouse was built on top of the Tunnel Ruins that lead to Venus Lighthouse, and indeed, through Babi Lighthouse is the only way to enter the main part of Venus Lighthouse.
