The spirits named "Dizmel" are unique, for they are born from the synchronization between dark-attributed micro-spirits and negative thoughts floating in the air. Because their birth is associated with negative thoughts, they are usually observed in eras with great wars, and they can barely be found in peaceful eras. If the density of their internal micro-spirits drops, they become low-ranked spirits named "Diz". Many Dizmels lead swarms of Dizes, and their forms of commanding low-ranked spirits grant them the title "Queens". By the way, because "Relics" is filled by negative thoughts, Dizmels are common species in Relics like how birds and insects are common in the outer world, and they float everywhere in Relics.
