Rispwind's Infinite Deep Dark

A small mod created within a day that provides a new function for Netherite! If you place a Netherite Ingot in a crafting table alongside an Echo Shard, you will be able to create "Echoing Netherite," an item that can be used like Flint & Steel to ignite the portal in the Ancient City! On the other side of the portal, there is an infinite Deep Dark biome with nether-based world generation.

WARNING: The portal won't activate if there are any Sculk Veins currently inside the portal frame. Remove the Sculk Veins and the portal should activate as intended.
