They are primarily a matriarchal society, fostering many Howling Banshees and female Autarchs. The gifted Farseers of the Craftworld labor long in their hunt for the hidden secrets of the Crone Worlds, hoping to secure both Spirit Stones and doomsday weapons that would tip the balance in their race's war of survival.
As followers of Morai-Heg, the blind crone goddess of the underworld, they constantly aspire to recover the long lost secrets of the Crone Worlds, the former Eldar homeworlds now residing within the Eye of Terror. Iybraesil's traditional colours are blue and white.
