Alhoon

Alhoon liches, also known as simply alhoons or illithiliches, are magic-using outcasts from mind flayer societies who have defied the ruling elder-brains, to achieve lichdom.

Alhoons combine powerful wizardry and sorcery with their innate skill at psionics to become a new threat to the established order of the Underdark and beyond. Their skin possesses none of the wet, smooth, slimy texture of living illithids, instead appearing dry, wrinkled, and cracked due to the powerful magic resistance that has prevented a perfect conversion to lichdom.

Alhoons are ignored, feared, and hated by mortal illithids due to their rejection of the illithid circle of life, culminating with the physical and psychic merging with an Elder Brain.
