C'tis is an Egyptian-like civilization of lizardfolk, available in all three Ages. It may refer to:
EA C'tis, Lizard Kings ← This one has Chariots, Dancers, and powerful 'Sauromancers' who've bathed in the Underworld.
MA C'tis, Miasma ← This one has Marshmasters, masters of Swampy magic, and the crocodilian giants they've accidentally awakened.
LA C'tis, Desert Tombs ← This one has reformed 'Sauromancers' from crypts in the desert, who can rally Early-Age mummies.
All three have Death magic, and their best Mages are found in all of their forts.
