Precursor

The most advanced and mysterious race to ever travel the stars. They ruled the universe 250,000 years ago, and then simply vanished. They left behind powerful artifacts, ruins, and a wacko race of planeteering tools who resemble fungus.

The Slylandro told that during their last meeting with the "shaggy giants" A.K.A. the Precursors, that took palce over 41 Drahn ago- that´s one *** of a long time- that they were described as being ´worried´, ahving found their "Answer", and being in a hurry to leave. This was approximately 250,000 Earthling years ago.
