Wolf Contract [WORK IN PROGRESS]

Origin
The Pack of Wolves originated at the three corners of the Wolf Country, Sky Country, and Claw Country, some say the only entrance between the World of the Shinobi, and the World of Summons they hail from, is hidden among the valley where these three countries border. Their home is a mountainous and mist filled place, roamed by nothing but wolves of all shapes and sizes. This is their home--their own world among the clouds and high peaks. The pack is ancient, coming from a time before Shinobi roamed the lands of the Shinobi World, the eldest of which still living are 1,000s of years old. Only once had they trusted humans over the years--writing a contract with a man of the Shinobi World, signed in blood. This contract has been lost for many generations beyond his life, until surfacing recently.
Lore
Rumors, whispers, and campfire tales tell of giant Wolves who once roamed the world. Very few times have these been seen, and even fewer believe the tall tales weaved by those who have. These apparitions of nature have throughout time checked on the progression of the Earth they are linked too, and fed these rumors throughout the generations. Very little is known by the public at large, only the ballads of their strength, and a hint of their origins. Stories say at the valley of Wolf, Sky, and Claw, is the home of these mythical Wolves, but the truth behind it all goes much deeper...
Culture
This pack of wolves has opened its doors to the outcasts of other packs, the ones chased away over territories, those who've been betrayed by their kin, the ones who've found no home until now. The wolves live in peace with each other, and rarely interact with humans. They have an elder wolf, the Alpha, who leads them in times of crisis. Due to their ways, there are many types of wolves who live there and make up those found in the Summoning Contract.
