The Saim-Hann craftworld is renowned amongst the other Eldar as a slightly wild and dangerous place. Whereas the other craftworlds have long since developed the Path of the Eldar as a means of self-control, in the Saim-Hann craftworld the Path is followed in a less formal manner. It is as if the inhabitants of Saim-Hann have a thin veneer of Eldar ways, covering the wild and carefree Eldar of old. Other craftworlds regard this as very dangerous because these are the very cultural traits which led to the Fall of the Eldar race.

Some Eldar even regard the Saim-Hann craftworld as a nest of wild barbarians living at the edge of Eldar society. The raucous, boastful warriors of Saim-Hann are aggressive, mobile troops, and skilled bikers. The speed and power of these machines is a symbol of warrior prowess, with young Guardians determined to out do each other in battle.

Saim-Hann means 'Quest for Enlightenment' and its symbol is the Cosmic Serpent. Saim-Hann troops wear red uniforms with details in contrasting black and white. Saim-Hann vehicles also favour a red scheme, often with vivid black or white stripes.
