Enderite can be made out of popped chorus fruit and Ender Shards. You get Ender Shards from killing endermites! You would need to upgrade Netherite on a smithing table to make enderite armor and weapons. Enderite armor and weapons would not only be better, but it would save you from the void! you can also upgrade an elytra to an Enderite Elytra, which doesn't need fireworks to fly and can hover! Not only that, but an Enderite Overpowerer (end crystal in the center surrounded by totems of undying close to it, enderite ingots around it, and a nether star on top.) dropped into the center of the end exit would make an Enderite Dragon, a metal automaton shooting Enderite Bombs, which explode, put dragon spit, and give you levitation. It has double health, and normal weapons don't work. Only Enderite weapons and explosives can damage the dragon. When killed, it drops a Shard of Awakening on the platform. The Shard can be used to open the dragon egg and get a tamed dragon. It can be fed with chorus fruit, and can wear enderite dragon armor. You can also trade the Shard to a Dragon Tamer, a villager who trades one Awakening Shard for 60 diamonds and 8 ender shards. Or you can use the Awakening Shard to turn Enderman into Ender Traders, trading resources, including Gemstone Obsidian, used to create an Ending Point, which uses purpur blocks to charge up and works like a respawn anchor.

That's all, folks!

Enderite Armor. It could give you the ability to teleport like an Enderman!

Hmm, that's an interesting question. As ender pearls allow you to teleport around, and shulkers can teleport too, I'd say that an ore found in the end would need to have something to do with teleportation, maybe allowing you to create teleportation pads or wireless redstone components like a hopper which transports blocks to it's paired counterpart instantly.
