That is Kepal, Elk Rider of the the Sun'aden. (The People)
The Sun'aden are a tribe of wild elves that live in relative isolation in their snow covered villages. Unlike their forest dwelling kin they do not have an abundance of natural resources to make their way through the long years of their lives. Instead each day is a fight for survival for these people. The winters are the worst. It is during this time of white that that game becomes even scarcer and these people balance upon the knifes edge of survival.
They are ruled by a leader called the Tul'Mar. The Tul'Mar is both a spiritual guide for the elves and their battle leader. He is advised by the three eldest elves in the tribe. These fiercely proud poeple though will bar no one from speaking to the Tul'Mar and stating what he or she thinks concerning this issue. This can lead to rather boisterous "discussions" within the chambers of the Tul'Mar while the poeple make their wishes known. But once the Tul'Mar has decided, his word is law. The Tul'Mar is chosen by the elders of the tribe, when the previous one dies or steps down.
They subsist through the hunting of game animals, and the gathering of the bounty of the forest during the meager spring they have each year. They cultivate the bushes and trees that grow berries, encouraging them to grow. When the berries are harvested they are crushed and added to the dried game meat to produce a past like trail ration called Lammus. This is carried by all hunters and scouts in skin pouches in case they are trapped by a sudden storm while they are away from their home.
Because of the harsh climate that these elves live in, causing high mortality, and the normally low birthrate of elves, children are seen as a great blessing. They are the great renewal of life, without them the tribe would die out. They are protected fiercely by the tribe and if a child is injured by an outsider, the entire tribe may mobilize to exact revenge. This reverence of children is extended, to a lesser extent, to all the creatures of the mountains as each child born is a renewal of the resources of the mountains.
The Elk Riders are the elite guard of these wild elves. They form a mystical bond with their mounts and are the first line of defense for the elves. They patrol far and wide around their settlement looking for any type of threat, their elk their only companion. When they discover a threat they will eliminate it if they can, or if it is to much for them they will return to their people and gather a sufficient number to destroy it.
No intruder is welcome within the lands of the snow elves, for even a few such intruders could upset the delicate balance between what nature can provide and what the elves need. Most such intruders are warned away by an Elk Rider that will seem to materialize from the blowing powder. Any that do not head this warning are dealt with more forcibly. The elves do not view these actions as malicious, it is a simple matter of survival. If it comes down to a group of interlopers that will not leave even after they’ve been warned, and their own people, they know who must be protected.
These elves bear a particular grudge against all goblinoids because of the abuse these creature cause to the fragile environment. Life in the mountains is harsh enough to maintain, but when orcs or goblins arrive they will strip a land clean, foul it beyond recognition, and then move on to do it again. These elves treat these creatures as a plague of locusts. A dangerous threat that must be eliminated, And the entire tribe may march to war against a particularly large band of them.
So with this as a background I’d picture these folks as very fierce, and very quite to outsiders. Saying what must be said and that it is all. They would at first be hostile to the party until they see the baby. At this point they would soften, allowing the characters back to their villiage and would help them. Always for the sake of the child they would say. It is a this point the characters would get to see the softer side of the elves. Amongst their own people and with their children.
When it is discovered that the party is being chased by the orcs, either initially, or later after they’ve been brought back to the tribes home they will see the fierce snow elves marshalling for war. The characters will have to assist the elves in destroying this threat since they are the ones that have brought this plague to them.
Hmm, longer than I had set out for. Sorry. I just get long winded sometimes. Let me know if this helps or if you wanted something different.
