The two and a half billion crooloyans live in less than two dozen juggernaut cities. The rest is wilderness with a few archeological sites spread across the planet.

Crooloy's heavy gravity made sliding and slithering the mode of transportation, so most of its native inhabitants have long snake-like bodies instead of feet and a well developed musculature. The only exception are the N'emmadrall - a strange skeletal arachnoid, with 12 instead of eight legs and a confusing pattern of rips, spines and ridges. Crooloy Arms copied its design for a war droid.

Crooloy's cities have ramps instead of stairs and display a lavish use of transport platforms, elevator pods and conveyors.

A remarkable spot in the system is Fallod. A burned out star, turned into the outermost planet of the system. It feeds most of Crooloy's hyperspacefaring ambitions with the required heavy materials. It is still highly radioactive and emits heat. It is unknown, whether it used to be in a dual star system with Menot I or if it was caught by its gravity. The dense and extremely slow moving body is very far away from Menot I and it took crooloyan scientists a long time to realize, that it actually orbits their sun.
