The Frostbound Relic is a small, intricately carved piece of ice that never melts, regardless of the temperature. It emits a faint, icy glow and feels cold to the touch, even through gloves. The relic is incredibly durable, able to withstand extreme pressure and impact without breaking. It also has a unique property of resonating with supernatural ice energy, causing it to vibrate slightly when near powerful sources of cold magic.

The Frostbound Relic serves as a guide and protector for detectives navigating the treacherous terrain of Art Dye's course. It helps them locate areas of strong supernatural activity and shields them from harmful ice magic, allowing them to uncover the truth behind the ice phoenix's return.
