The last of the tribes are the Seraphin, who to land based Seodalis are usually nothing more than a myth.
Thought by many to be mythical, magical beings of elegance, and grace, the Seraphin are actually just very, very lazy and unpleasant.
Meeting one for the first time would be a shock to any of the other tribes for more than one reason, after the initial amazement of seeing a real Seraphin, they would realize that these Seo's are not at all like the stories describe.
Seraphin's are rude, arrogant and want absolutely nothing to do with the quarrels and struggles of the landbound tribes.

Their pelt colors are strictly pure white, or pure black, with golden markings. And they have a large pair of feathered wings on their backs.
They have long, fluffy tails, rounded upward facing ears, and are the tallest of all Seodalis.

They are mostly solitary, and their numbers are few, usually choosing only to live with their significant other and/or immediate family.
Seraphin are completely naked all the time, as they have no need for clothing and think it detracts from the beauty of their gold markings.

Their "armor" is badly made, and has no protective qualities whatsoever, why would it need to, when they never participate in battle.

Mostly, Seraphin are spoilt by the easy life their tribe has been given, and look down on all the other tribes, both literally and figuratively.

An example of a typical Seraphin Seodalis, Seodalis are a closed species owned by me.
