Natura is a mod that aims to spice up the world with interesting worldgen. With a few small additions, hunger no longer has to be about hunting animals early game. The mod is mostly intuitive; everything should be sensible or explained in-game.
Natura is a worldgen companion to Tinkers' Construct. The mod works well with ExtraBiomesXL and Biomes O' Plenty, but neither are necessary for the best experience.
This mod requires Mantle.
