The Golden Age is a ServerMod for Minecraft which will soon reach alpha-status. Goals are: 1) Slowly building the world of Weyard, 2) Add Golden Sun-ish RPG mechanics and lore, 3) Expand on and improve the traditional Minecraft experience.
The mod itself will concern itself mostly with adding items. The mechanics will be based on multiplayer and Sponge.
