Design a tropical island spawn centered around a large volcano as a visual focal point. The main island should host a structured plaza-style Crates Area, EV Training Area, Main Raid Arena, and a smaller Player Fighting Arena. Include a Gym District featuring 18 gyms plus a reception building, and a 5-floor Battle Tower with 4 NPC battle spots per floor and its own reception. Add fully furnished PokéCenter and PokéMart buildings, a Safari Reception building that functions as an NPC teleport point, and a separate VIP battle area where ranked players can fight select NPCs for free levels. The layout should feel cohesive, immersive, and optimized for player flow.
