The rift that opened over Fortnite's map in the lead up to Season 5 has started closing, but that doesn't mean everything is going back to normal. As of update 5.30, the rift has shrunk significantly and turned a malevolent shade or purple. Even more eerie are the lightning strikes players are reporting. Take a look at the footage capture from LootLake.net below. 

Much like Season 3's meteor shower, purple streaks of lightning are landing all over the map, and seemingly at random. With Tomatohead reappearing as the overlord of a saucy cult, chances are that something bigger is happening soon. At the very least, this marks the beginning of a thematic shift towards Season 6. Time sure flies, eh?
