Apalachia Blocks are the solid blocks made from the crafting of 9 Apalachia Fragments. The main purpose of Apalachia Blocks is to be used as the portal frame to the Skythern Dimension. However, Apalachia Blocks can also be used as decoration.
The portal to the Skythern Dimension is made of Apalachia blocks. It is made in the same fashion as a Nether portal, requiring a minimum of 10 Apalachia Blocks, which equates to 90 Apalachia Fragments.
