A while ago, there was a datapack called "Aether Bosses". This datapack contained The Aether 1 bosses in Minecraft, able to be summoned by pumpkins and stone bricks/iron block/gold block, a while later, I can't seem to find the datapack, does anyone know what happened to it and have acess to one?

Edit* - Before anyone say anything, there is no Aether for 1.16.5. There are a lot of good mods there...
