The Saim-Hann are a Craftworld of the Eldar in Eternal Crusade.
The Eldar Craftworld of Saim-Hann was one of the first Craftworlds to abandon the Crone Worlds as the Fall of the Eldar approached, heeding their Farseers’ warnings. As such they have spent far more time isolated from the rest of the Eldar than the other major Craftworlds.
The Saim-Hann are fierce warriors, who place upon honour a higher value than their sophisticated kin. They are known for their preference for fast, mobile warfare, striking as a serpent before falling back beyond the reach of retaliation.
