Fallen stars

Info
Once 100 fallen stars have been collected after moon lord has been defeated, a star in the middle of the screen will start to appear to grow and shine vigorously. The player will also have an ingame message. "a bright light appears in the sky."

After 10 days, the star will grow to its maximum and it will descend toward the side of the world where the dungeon would be. In the background an explosion would occur and the player will get an ingame message. "the air begins to burn."

The Fallen stars biome will begin on the surface between the natural snow, jungle, and world evils biomes between the dungeon. The biome will only spread vertical from its farthest right to left block. It can be spread using the shiny solution with the Clentaminator.

If there are other biomes examples given as underground snow or mushroom biomes. Then lucky you, because you get some sweet special enemies spawns and rare ores and items. Glowing mushroom biomes become Shining mushroom biomes and snow and underground snow biomes become the Bitter snow biome. The underground jungle will be converted into starstone and stariol.

Prehardmode ores are converted into shining rock, Hardmode ores are converted into post moon-lord ores                      Cobalt and Palladium are transformed into Staraltium, Mythril and Orichalcum are transformed into Costhricum, Titanium and Adamantite are transformed into uniquimite.

On rare occasions naturally spawned chlorophyte can be instantly converted to Chlorodium. The player can also place chlorophyte ore surrounded by shining rock to convert it into Chlorodium.

Luminite can be placed surrounded by shining rock to convert it into Luminatite.

Stats
The Fallen stars biome surface at day will spawn Fallen stars specific enemies. While at night enemy spawns vary from different celestial event enemies that will only spawn on the surface.

The cavern layer will spawn any worm related celestial event enemy and will spawn Star catchers, Cosmic wyrms, Asterwraiths, and Asteroid heads.

The surface layer will spawn ground humanoid beings from each celestial pillar randomly, and at night any celestial enemy could spawn. Biome specific enemies include carbon slime, split being, and Meteorite head.

The three bosses that relate too this biome will be Portal being, Tentracald, and post Tentracald, shining mushroom specific Paralyzerath.

Note
This page is not completely finished I want to sprite these myself but I have no idea what software to use. Does anyone have ideas?
