Perhaps a month of posts was too ambitious. Ah, well, nevertheless: GLOG is about breaking the rules, and thus I shall finish GLOGtober as though it never ended.
The Civilized Lands
2. Orc: Tall and universally muscular, with strong brows, jutting lower jaws with protruding tusks, and pointed ears. There are three races of orc: Hill, water, and “half”—the lattermost of which would more properly be termed “mountain orcs”.
1. Hill orc: Green skin, approximately seven feet tall, +1 STR.
2. Water orc: Heavy-set, gray-brown to blue-gray skin, bulbous milky eyes, webbed extremities, gills set into necks and faces, just under seven feet tall. Amphibious (swim speed equal to land speed, breathe water as well as air), see well in dim light, disadvantage in sunlight, +1 STR.
3. Half-orc: Pale yellow, green, or gray skin, about six and a half feet tall. “Half-orc” is a (derogatory) misnomer applied due to relative size, +1 to a stat of your choice.
Orc social systems and biology are closer to our own than those of goblinoids, so I don't think I need to spend as many words on them. Hill orcs are the ones you probably think of first when you think 'orc' - big, green, etc. This is by design, of course - the imperial dynasty is of hill orcish origin, and by tradition members of the Imperial Court are selected from among the population of the majority-hill-orcish provinces at the empire's heart.
The River Kingdoms
A large archipelago kingdom, tropical and subtropical in climate with some mountainous regions temperate by way of altitude. One of the most important vassals of the Imperial Court for much of its history, providing a great portion of its food and art imports and respected as such in the Imperial Core. Majority water orc.
A smaller vassal kingdom and buffer state between the Imperial Core and its neighboring powers, located along a coastline and stretching inward along several major river tributaries. Ked provides a greater proportion of its population to the imperial army than any other River Kingdom, and several of its people hold high generalships. Majority water orc.
An empire in its own right, laying claim to a storied history nearly as long and rich as that of the River Kingdoms as a whole. An island nation far removed from the Imperial Core, it occupies a special place in the complex diplomatic structure of the empire as a nominal ally rather than vassal or tributary. Majority mountain or "half"-orc.
A recently-acquired imperial possession - a state of affairs which few expect to last, as the mountainous region is a historical enemy of the River Kingdoms and has been subjugated before only to re-achieve independence in a long and bloody cycle of warfare and revolution. Majority hill orc.
