Build a massive floating archipelag...

Build a massive floating archipelago of jagged glacial ice spikes and frozen tundras, set at 250% scale. The arena consists of 5 distinct floating islands connected by colossal, translucent blue ice ring tunnels. Design a long, winding race track that loops around a central, shattered frozen comet. The track includes steep vertical diving shafts through hollow icebergs and sharp U-turn canyons carved into blue-packed ice. Scatter floating lanterns encased in ice along the track to mark the flight path. Decorate the edges with weeping icicles and aurora borealis particle effects in the skybox. Ensure the start/finish line is a grand frozen palace gate with high visibility.
