Create a 200x200 block Minecraft world designed as a small inferno-themed PvE arena. The entire area should have a volcanic, lava-filled atmosphere using blocks like blackstone, basalt, magma blocks, netherrack, and lava. The terrain should be uneven with small lava pools, cracked ground, and rocky formations, but still fully playable and easy to navigate. Surround the map with tall dark stone walls to contain the area. In the center of the map, build a medium-sized infernal fortress or citadel that can function as a boss arena. Keep the design compact, detailed, and optimized for PvE combat, avoiding excessive lava that would make movement frustrating. The world should feel intense, dangerous, and hellish while still being balanced and fun for multiplayer combat.
