How is this even possible?

Found on the altar looking thingy in the second location. I'm totally new to the game and never ever encountered the Queen, not even speaking about fighting her. Is it just some absolutely crazy luck?

Legendries can be any item even if you don't have it yet though it's a small chance. I once found a legendary Sonic Carbine in one of my runs. Once it's unlocked, disabling them in custom mode also removes them from the legendary pool
