Undergarden Mod is a mod that allows us to access a new dimension, consisting of an underground world located beneath the Bedrock layer. This dark dimension is inhabited by new vegetation and monstrous creatures, forming part of a chaotic and mysterious realm. The Undergarden is a dimension that we can explore in search of new adventures. In this new world, we will find new mineral resources with unique characteristics, enabling us to create new sets of weapons, tools, and armor pieces. To access this new dimension, we will need to construct a dimensional portal in the same shape as a Nether portal but using Stone Bricks instead of obsidian. The portal can be activated using a new item called the Catalyst.
