Looking for a fantasy series where gnomes, elves, humans and dwarves must band together. The fantasy series has gnomes who raise an ancient evil. A wizard is trying to become king. Humans, elves, dwarves & gnomes band together. A young gnome woman finds a dog that she thinks is a wolf, so she names it Wolf. The wizards have some magic plant that makes people work harder. Elves and dwarves are set to invade the gnome tunnels.
