Purple Rain is an NPC standing at the top level of the Wooden Fortress in The Heartlands. His dialogue suggests that he might be a singer, but it is not known why he is standing in the middle of the wilderness instead of continuing his career. "Purple Rain" might be a reference to the song of the same name, by Prince and The Revolution. He is the quest giver for the quest We'll Fix It In Post.
