Tond

Tond is an alien planet and home to a humanoid species called the Yarkdao, which build cities out of blue metal and black stone. It's in orbit around two suns: a green star named Yifne and a "dead star" named Baalblo. It's also one of the many worlds to have been visited by Glaaki, prior to its arrival on Earth.

The brain-preserving crustaceans from Yuggoth are also active on Tond.
