Rock and Stone

Dwarves, cool people who just like to mine

Elves, horrible evil people who live in the forest coming to destroy the dwarven town

The Dwarves decided to defend by building a ginormous cannon to blast them away but because Dwarves only believe in using the best materials they have a limited supply of cannonballs and it is the same material that they use to repair the town and also improve the cannon. Shoot Wisely
