Cathimi, the

From the 1991 Galactic Sketch collection
this is an early sketch of a Cathimi. Aka the Seeders of the Reih -

the Cathimi apperar in the second arc of GC stories and are  humanoids with TL 10, presumably native to distant Super Cluster (The largest structure in the universe is a supercluster of thousands of galaxies that may stretch for up to a billion light-years across the heavens,) probably the  Supercluster Phoenix

They are very elusive and secretive, but not agressive. (they do defend themselves) and have equally rejected closer interaction with the Union and the Tomradi. The first contact with Cathimi, occured on Planet Avondur.

Physical appearance:
Observed individual seem all of the same height (200 cm) and have no outward features to differentiate them individually. It appears they also have no distinctive gender. They describe their gender as "Das" and made no reference so far of a second different gender.

Their skin is of a gray shade.

Other
They exlain their presence on Avondur, as a mission of waiting for the Purpose. No other explanation was given.

The Cathimi encountered are, acording to Tyr, psionically wiped and do so whenever they leave their ships.
