Corrupted Seasons

Seasons are gone mad!
Corrupted Seasons is a Hard mode Event summoned when World cleaner is killed by player in Corruption/Crimson while World cleaner is searching for his Galaxy in a bottle. It is similar to Lunar Event,cause 4 bosses will appear in world,and player must kill them,but this time they will appear in one same place every time this event is summoned.

Four bosses are Spring,Autumn,Summer and Winter. Each of them will appear on one same place on surface:

Spring:Hallowed-New,lovely and poisonous flowers are growing under the Moonlight!

Autumn:Jungle-Its not Blood Moon,but its raining blood!

Summer:Desert-Corpses are melting under the power of Sun's fire and Moon's anger!

Winter:Snow-Beasts are freezing while Moon is unable to send his tentacles to shine them!

After all bosses are defeated:No...Never...HOW?!

Also,when each of the bosses is killed,message will appear,and it will make a small difference in the biome they resisted.New biome will lead the player to next and final fight in this branch of the game that starts with Aquarian Horde.
