Thronos

An island south of the Fangs, home to Neesha, encountered in Initiates. GM notes:

Thronos is small, just 15 miles across, roughly round (another old volcano). Like others rocky central highlands, sort of rounded on top, rather than a peak. That dome of rock is split down the middle, creating a 2000' deep east-west crevasse that extends most of the breadth of the island -- on the eastern shores, the crevasse reaches the sea, a 50' wide inlet that extends most of a mile. The western slopes are intact, with the crevasse narrowing to nothing a few miles inland.

The eastern shores of the island are steep and craggy and green, inhabited by a type of mountain goat and various monkey species in the trees, preyed upon by huge snakes.

That western slope is covered in the hardy crops that "Throtians" have cultivated for centuries.

Those people have split into two tribes. To the north of the crevasse, the "serpents", or "lesser Throtians" have blue, green, gray, or violet eyes. (from the north's perspective, they are the "chosen", or Greater,, and the south are the "dogs", or lesser)

In the south, the "greater Throtians", or "the people" have brown eyes.

The serpents and the people enslave one another when captured, and if you're born with the wrong eye color, well, baby and mother are killed or cast out.

Both tribes revere child-bearing, and Neesha feels terrible that in her last 4 years of servitude, well, she could have graced her people with maybe 5 new babies...

Both tribes refer to the crevasse as "The Rending" and the oral history is that the split between the tribes is not just symbolized but directly associated with the crevasse -- that some ancestral divide nearly cracked the island in two. Besides being virtually inaccessible, it is forbidden.

The western croplands are contested lands. But over the centuries, the serpents and the people have come up with a system -- after fall harvest, an armed conflict called "the Balancing" is ceremonially conducted. 25 warriors of each side fight to the death. To the winning side goes the rights to the land until next fall harvest (the ninth full moon since the shortest day).

And, in the crevasse, is a hellgate, open, with 50 voidbringers...
