Monoliths of stone, 155 ft. wide × 39 ft. deep × 350 ft. tall, are scattered across the continent. They are all the same size and shape, though they are made with different types of stone. They are used as gathering and meeting places for clans because they can be seen from a great distance. The origin of these monoliths remains a mystery, and these do not exist on the other known continent, Takela.

This is a hat-tip to Space Odyssey.
