You've just beaten Plantera, and were visiting Trixy the Party Girl when you found a strange... butterfly. You cocked your head but shrugged it off, killing it. It was around 8:30 PM, and you wanted to head inside to grab some food or at least sit down when... You hear strange music.  A being materialated(hold up-) materialized into the air, in bright rainbow light. This thing, she, you realized, looked down at you. Strange projectiles of light fired at you. "Woah, oh god-" you flew up, making them miss you. You take out your sword, preparing to hit her. But instead, as you dodged attacks, you curiously look at her, studying her. The healthbar in the air reads "Empress Of Light," so you call her that for now, in your mind.
