An Eternal of Sothis (originally known as Djet Sopdet) is a Follower of Set who has lived through an entire Sothic Turn, meaning exact 1460 solar years. This is the age a vampire is considered a Methuselah.

Eternals are revered as demigods by the Clan, whose words have the authority of the Lord of Storms himself. An Eternal is counted as a direct childer of Set, regardless of his actual lineage, although the Setites explain that this is more of a metaphor to explain their exalted state.

Among the Eternals are the Hierophants, the most ancient of Setites and the true stewards of the Clan in their god's absence.
