The Leng

A mix of different species that combined together to form a symbiotic society ruled by lawful evil intent. The society consists of spiderlike spell casters and short humanoid traders, along with other less common groups. They practice void magic and worship any powerful creatures of the void or astral sea.
The Leng have been at war with the Aasimar of Andel for thousands of years, though periodically they find a balance of peace and do not outrightly attack each other.
