Characters start at The Core in the centre of this small circular biome. Unlike the other biomes, it shows no name at the top right of the full map screen. The same as the neutral boundary areas between all the other biomes, to which it is connected.
Patches of Ground Slime spawn Orange Slimes which are not aggressive until first attacked, but rarer Red Slimes are will immediate chase if they sense a foe close by. Fungal Soil respawns Mushrooms, for easy farming complicated only by similar looking Shrooman, whose enthusiastic charge attack is more cute than dangerous.
Various Scenes may spawn in this area with extra loot.
