Create a Minecraft server hub calle...

Create a Minecraft server hub called "HaVa Central" with a circular, symmetrical layout and an End-themed purple and black palette. Build a central spawn platform using obsidian, crying obsidian, and blackstone with glowing accents like amethyst and purple glass. Add a centerpiece such as a floating End crystal or beacon beam with pillars. Include 8 evenly spaced portals in a ring using crying obsidian frames and purple glass for different game modes. Surround the hub with floating End-style islands made of end stone and blackstone, with chains and chorus plants. Make it detailed, clean, and suitable for a professional server hub.
