So in this nonexistent mod, after defeating the ender dragon and actually picking up the egg (which the mod would let you do) you take it back to your base and build a little shrine for it. Out of 9 iron blocks in a square and a gold block on the iron you put the egg on top of it and put 4 redstone torches on the corners of the iron square and 4 normal torches on the remaining squares. Then the egg will start emitting the lights the enderdragon emits when it dies and it will pull you toward it. when you touch the egg you get teleported to another randomly generated dimension where a big village will spawn. it would be like a normal npc village but bigger and nicer looking with actual human npcs inhabiting it. In this villlage would be a mayor's house or king's castle or whatever. Upon entering and right clicking the mayor/king a cutscene like thing will show up like a slide show. It will tell of a red dragon frightening everyone when it flies over the village. The mayor/king will then ask you to go and get rid the dragon which lives in a large cave somewhere. The mayor will tell you that in order to find the cave you need a magic map. which is hidden somewhere in the village. when you find this map it will generate the large cave in an unloaded chunk and the dragon will be in it. The dragon will be in a large nest filled with a new straw block. in the nest would be a big blackish purple egg. to defeat the dragon you must light the nest on fire, which will burn the dragon to a blackish color upon which it would disintegrate to ash. The egg would still be there and when you tried to take it or right click it it would teleport away. You would then leave and go tell the mayor/king who would congratulate you and give a 32 emeralds, 16 gold ingots, and 8 diamonds. You would be stuck in this dimension so you'd probably just make a house and mine and continue on with the game. then around 14 minecraft days later you would see smoke coming from the direction of the village. you would probably run over there and try to see what happened. In the village everything would be burnt and on fire. even the people just burned husks. then you'd see a black shadow pass over the village and purple glowing eyes staring down at you as it passed. You then would get transported back to your old base with everything you had in your inventory and the shrine still there but the egg... empty.

I just wanted to give a little backstory to the enderdragon and the end. Ya know to make it a little cooler. If you like well... good...I guess.
