The site of a horrible battle, centuries ago.
That's the short form.
The long description is worse.
Nearly every cloud-island (Major or Minor) sent warriors here. The conflict was initially about self-determination, self-rule, for this island, freeing themselves from the Barathi yoke. Alas, other political issues came to the fore. Internal conflicts in Viridia, freebooters from both Colronan nations, and a large contingent of Kroyu fighters, trying to re-establish a homeland for themselves.
It was bloody. It was bad. It was a shame.
