Lunar Events

The Lunar Events are a series of Hardmode, post-Plantera events initiated by defeating the Lunatic Cultist boss. Once the boss is defeated, several surface biomes show a large moon in their backgrounds, and spawn several unique enemies. The version of the event battled depends on the biome the player is currently in, and can be switched by traveling to a different biome. The events can be escaped by retreating to a Forest biome.

Each of the four variants has a different theme, along with a corresponding Celestial Tower variant that acts as the centerpiece of the event.

The variations are as follows:
 * An orange/red moon displays in a surface Mushroom Biome.
 * Solar Pillar
 * Drakanian
 * Corite
 * Sroller
 * Crawltipede
 * A greenish moon with an alien-like theme.
 * A purple moon displays in the Corruption biome.
 * Nebular Pillar
 * A white moon displays in the Snow Biomes.
 * Stardust Pillar
 * Star Cell
 * Flow Invader
 * Twinkle Popper
 * Milky Weaver
