Rift

The academy building. Everyone knows they exist, but nobody knows what's inside them. Increase your depth level by improving the expedition that delves into its dark sides. Each next expedition will allow you to unlock upgrades for the village. Improvements will guarantee acceleration of farm work, shortening construction time and accelerating token mining.
