The main character of this story is a Summoner, but unlike any other summoner you can only summon one powerful beast which is a huge wolf. You'll travel around the world in a look out of your family that has been taken away and you are out to save them.
This wolf will do anything as you command but only for a limited time, when the time limit is up he will despawn and you have to let it rest for awhile before summoning him back. If you summon him before his resting time is up, he'll be weaker and will be out in a shorter amount of time than before.
In combat the wolf can attack and deal massive damage and protect you from harm. In puzzle side of the game, he can push heavy boulders and be the bridge of things that are far of reach or you can also ride the wolf when needed.
