Luxu eggs radiate a calming aura. It's said that if you try and remove the egg's hat, you will feel an overwhelming melancholy.
Luxu are very docile and helpful creatures, learning how to interact with others at an early age before becoming a professional spirit guide and guardian. Using their staff to attract lost spirits and guide them to the other side, a single Luxu will guide as many as 5,000 spirits in their lifetime before they are stationed as guardians in the spirit realm. They have been sighted wandering around fogbound lakes in the forests though their place of origin is largely unknown.
