Bears Bears would be large neutral mobs with a lot of health and a decent attack due to their large claws. They would attack sheep, cows, boars and other "meaty" animals. Due to this reason they would be unpopular with many farming NPCs so they certain factions would attack them on sight. 3 variety's would spawn: Brown, black and polar, and each would have their own specific drops. Each would drop their own colour pelts which could be crafted into armour on a regular crafting table as well as dropping the remains of their last meal I.e fish meat and bones. This would look a lot like wart fur armour ,but in brown, black or white, with an impressive Bears head as the helm. Brown Bears would spawn in forest and woodland, blacks would spawn in foothills and in special caves in the mountains and polars would spawn in the forodwaith.
Seals These blubbery animals would spawn in the cold North and be the prey of both the polar bears and forechel fishermen. They would drop seal meat and blubber which make up most of the fishermens diet as well as their regular armour set.
Forechel These icy fishermen would roam the Northen lands. Their would be a few NPCs: the regular fishermen, the warrior and the chieftain. The fishermen would trade fish for southern goods and the Warriors would be decked out in full forechel armour ( made from seal blubber ) and use forechel bone equipment. The chieftain would wear a full set of polar bear armour and sell you troops, for a price. They would have their own crafting table snow and ice brick and would live in igloos in the forodwaith and wooden huts in the northerly tundra.
