Minecraft wiki entry for Multiplayer_PvP_bases, associated text: Your enemy's base is in the sky, on a floating island. There are 5-block thick walls, with an obsidian layer, a liquid layer, and a checkerboard layer. All the players are inside, and their dispensers are filled with lava, to pour on raiders trying to pillar up. There are traps on all the chests, and the enemies have Punch II bows, splash potions, and Channeling tridents. When you go raid the base, it is a thunderstorm and no one will sleep through it.
