The Lake of Fire was a body of lava-like molten protodermis in which the village of Ta-Koro was situated. It lay inside a deep trench in Ta-Wahi and was part of a lava flow that extended from the Mangai volcano in the west to the shores of Ta-Wahi in the east. Ta-Koro sat atop a pillar of rock that rose from the center of the lake. A series of rock pillars could be made to rise from the lava to form a bridge that connected Ta-Koro to the eastern shore of the lake. The villagers could lower the bridge into the lava when the village was threatened.
Notes
The Lake of Fire was a molten body of liquid protodermis on Mata Nui and the site of the village of Ta-Koro. The superheated lava was spanned by a bridge that could be lowered into the lake when danger threatened.1
The village of Ta-Koro rose from the Lake of Fire near the mighty Mangai Volcano.2
The lava near Ta-Koro was actually molten protodermis.3
