Hollow
Compound current, step 1· scorched emptiness
Hollow is a scorched place where a current has nothing to hold on to. There is most of it in the End: the dragon and its egg, the End portal, endermen and shulkers. On a lens Hollow opens a Washout through stone, in ink it makes Unload, in inscription Infinity. It brings notes of the Stillness. It goes into five combinations.
