The Last Four Elemental She wolves

The werewolf kind is running low on wolves due to the last war that killed all the she wolves making the werewolf population run low on pure werewolves. The moon goddess couldn't bear to see the werewolf population end so years later she creates four she wolves.

But she knew that by creating them they will be in danger so she gave them each the power of the four elements to protect themselves.
The oldest is water, the second is fire, the third wind and the youngest is earth. She also decided to make them the daughters of the king of werewolves, so they can grow up to be able to do what they created to do.

War was about to break and the four she wolves were training their lives out and became the top four warriors of the pack. Then they were needed by four packs who almost lost against the vampires.

But then Ash and Van get kidnapped and loose their memory til two years past and the only two who can help them remember is Dylan and and Mathew.
