I made a few craters...
I replaced most of the ender crystals with air blocks.
I also fixed a few islands of that glitchy 'Endstone' Block with Air blocks.
In fact, I built a shrine of bedrock surrounded by torches with some end portal.
But seriously, I was playing on creative with Throwcraft.
TNT Bombs + Firebombs + Water + Lighting + Lava + Creative makes the End a very... interesting place.
