Yhhanak'ukul'lanjh

The Yhhanak'ukul'lanjh are an extinct space-faring civilization. They discovered the Omicron Hygeras Object and left a warning beacon in the area about the object to deter curious sapients. It is possible that the object's appearance, roughly 400 million years ago, resulted on the Yhhanak'ukul'lanjh's extinction, as it is thought to have caused several mass extinctions in its vicinity.
