Haiyang Sea? Goombac and I - 'scuse me - the Wuqiongi and Ondeetien have that as a shared etymo-illogical misunderstanding. It fits with the whole way Ondeet got named.

If you got the Ocean Sea straight from approximate Chinese I'm impressed :-).

The Ondeetien would rather trade than fight, "these days", but nothing says there mightn't have been past conflict. But more importantly - just what sort of cheese do your near-Equatorial fromagiers produce, that Ondeetien upperlatitudians need?
