Colonel Z.e.r.o. wins one third of a cookie. The true form of the nomads is ever changing, very few seen them. Less to tell the tale, whereas most have only dead to reveal the identify from the encounter with the Nomads. Worm-like beings? That's their past, but their present and future are staggering (based on the leftover conceptual artwork). Some will see them very soon... :-) Have a bit of patience.
