The Twilight Realm

This datapack changes the world's general ambiance (or only a part of it, you decide!), with feature from the twilight from Zelda Twilight Princess:

• Darker, more yellow sky
• Particles from Zelda: Twilight Princess recreated
• Yellow lighting
• The time passes, but it always look the same: same light level, hostile mobs always spawning, never burning...

You can manually set a biome to the twilight realm with /fillbiome, but the whole world is affected by it by default

It also adds shadow beasts, which spawn through twilight portals, spawning at a random player
