Design a massive underground DonutSMP stash base in a black and crimson color scheme. The base should look like a war bunker mixed with a demon fortress. Use obsidian pillars, blackstone walls, lavafalls behind red stained glass, redstone lamps embedded in geometric floor patterns, and a circular main vault room with layered storage walls. Add a secret entrance hidden under a normal survival house. Include trap defenses and a hidden panic escape tunnel. The atmosphere should feel powerful, illegal, and intimidating.
