"i need a detailed and mystical background focused on a tic tac toe board, embodying the essence of medieval magic. imagine a dark, enchanted forest as the setting. in the center, there should be a robust, ancient wooden table or stone pedestal, illuminated by ethereal lights or candles, where the game takes place. the tic tac toe grid itself should be carved or etched into the surface, surrounded by arcane runes or mystical symbols that glow with an otherworldly aura. elements like hovering, glowing orbs, creeping vines, and ancient artifacts can be included to enhance the magical atmosphere. please focus on making the tic tac toe board the central element, ensuring it's clear and prominent, with the magical, medieval theme complimenting it."
