Lore
Dear Terrarian who is reading this I am Valdaris. Nothing more, nothing less. A Harpy. I'm writing to warn you of this man in a green shirt, blue pants and with orange hair. He looks like a Guide, or a Terrarian, but he is neither. He is a demonic entity beyond space and time that you should avoid AT ALL COSTS. Do not make contact with him. He will prey upon your mental weakness to plant the seeds of delusion in you. If you listen to his words, in time you will be his slave. And if you resist... He will destroy you.Just avoid him. For everyone's sake. Less another floating island cluster gets vaporized, and the cartographers have to scratch their heads again.
