Ferius is Ossval's nearest Moon. It has a slightly less substantial gravity well than Ossval although this only extends a tenth of the distance from the surface of the world. It's atmosphere is thick and rich with oxygen, and is starved for carbon dioxide. A bright green coloration suggests to the observer that it is covered with some form of photosynthetic vegetation and this is a well confirmed fact.
The most dominant form of life on Ferius is a thick green moss which seems to cover everything that does not move, quickly. Rocks, bamboo, and even tree sloths have been known to act as a foundation for this barely edible growth.
The fauna of Ferius is positively prehistoric. Wild Moon Elves roam in nomadic familial clusters predating upon roving herds of Irish Deer, Mammoth, Mastadon, and Bison. Huge beasts such as Megatherium, Tigers, Hyenadon, and Darthyr Sphynx hunt Moon Elves and white tail deer as they present themselves.
There are no known and confirmed permanent civilized settlements on Ferius, although this is a subject which is debatable. Elven tales tell of plasmoidial beings who slog endlessly through vast mossy phosphorescently lit subterranean cave complexes. The creatures themselves are extremely violent and sadistic with regard to what they consider to be prey animals, such as Elves or anything non-Xexis. Whether the Xexis congregate in towns or cities is purely a matter of conjecture but it is assumed to be so due to their apparent high technical level of advancement.
The flora of Ferius is mostly Bamboo or other hardy grasses. Trees do not exist on this Moon and no mention of them ever having lived here has been passed down through the epic tales of the Elves. There are absolutely no flowering plants on the whole world. No ferns, no fungus, no algae. There are lichens and mosses in great abundance, and the grasses come in over seven hundred different varieties from the 35 foot tall stout bamboo to the swordgrass, down to the low growing worzet grass.
The Moon Elves rate as the second most influential race upon the whole of Ferius both technologically and numerically. Their society is capable of speech, rarely copper tools, but mostly they are a stone age society with some magics to suppliment their meager existences.
As far as customs are concerned, Ferius is a world fixated upon hunting and prey. It is a wild world with very little in the way of culture. Most Elves and Alaghi exist poised on the brink of their own mortality. Few Elves ever reach their maxium age.
One Elven cultural trait which is in evidence on the whole of the lighted side of the Moon is that the history of the clan is closely guarded in the form of great verbal epic tales. Each time an event of the proper magintude occurs, it is added into the history of the clan. Unfortunately, these historys are not kept by all the members of a clan. Only a few Bards of a clan are trusted to safeguard the lives of the ancient ancestral storys.
One of the greatest and most irreparable blows which might be dealt a rival clan is when it causes another to lose it's Bard's. With them goes a clans past and the survivors of such a society rending calamity become a past-less group of wandering outcasts scattered in shame.
There is no written language amongst the Moon Elves and all magic is symbolically conveyed. Most symbols are tied to the constellations or stars, so that if someone were going to invoke the memorization of a spell, they would gesture and meditate upon and to the corresponding sequence of Constellations, Planets, and Stars needed to supply a written component of the spell.
Clothing among the Moon Elves is mostly tanned bison leather and only needed to cover one for the purpose of modesty or utility. No armor is worn nor has any ever been developed. No shoes or sandals exits either.
The Xexis and their formless spawn would clearly be considered dominant if they could be counted properly. While not thought to be numerous, they are known to be technologically superior to all life on Ferius. They burrow through the ground collecting jewels and metals. They are belived to dominate the entire darkside of Ferius. Their arcane might is unmatched. Powerful dweomers defend the entrances to their underground dwellings preventing even the most curious and foolhardy of Elves from entering there.
While the Alaghi are perhaps the oldest race on Ferius, they are far from assuming anything apporaching a dominant role upon their homeworld. The Alaghi exist mainly as scattered socially detached hermits and scholars. Rarely they can be found assembled as clans of viscious ignorant cannibals, preying on their own gentler cousins as well as the Elves and Sphynx. Of course, nothing but a Xexis could eat a Xexis, and so they are avoided by the cannibals, but they are the rare exception. This does not mean cannibals will not slay Xexis whenever they think they can accomplish it.
Ferius itself endures a vigorous eight hour day. It circles Ossval three times each twenty four hour period,(Ossvalian Day). Some civilizations on Ossval liken its passage to a feral beast hungrily searching the sky for scarce prey.
Because or its rapid orbit, Ferius has three short,"Nights" which are actually Terran Eclipses. The twilight of these eclipses last one half hour separated by a full hour of absolute darkness at the height of the eclipse.
To add to the capricious nature of Ferius is it's rotation schedule. Ferius rotates in equal proportion to its orbit of Ossval, thus leaving it with one side which is always turning it's back to Yhrniia in utter darkness and the other always,(save for eclipses)turning its shining happy face into the warm light of Yhrniia,(The Sun).
The dark side of Ferius receives a two hour period of sufficient reflected light from Ossval's surface to produce a twilight for a half an hour interrupted by one hour of near full daylight per,"Day" or eight hour period.
Rumors abound about the nature of life on the darkside of the nearest moon. Debates periodically rage as to why it maintains a green hue whenever a new theory surfaces. Most would agree that whatever vegetation survives there, it must do so with the six hours of light it receives in an Ossvalian Day,(24 hours) or it must utilize chemosynthesis or both.
