Helm made of a mysterious substance found by Team Adventure in the sprawling cave network under Seattle’s Ork Underground. The Serpent Crown causes all who see it a compulsion to put it on. It appears to be inhabited by the spirit of an ancient water dragon. While possessing Blip, the dragon spirit told Team Adventure that he was manipulating ghouls in the underground in an attempt to face an enemy, like him, from long lost eons. Blip experienced several of the dragon’s memories of a city beneath the ocean and a war fought across space and time.
Later, during Team Adventure’s raid on the Dunkelzahn Institute of Magical Research, the team found an Atlantean dragon skull on display in the museum. A curse on the skull caused a death spirit to materialize. Ji-nan battled this spirit while Blip and Professor J were stealing the Sextant of Atlantis in the research wing of the facility and she took the skull before they left.
Ji-nan and Blip returned to the caves beneath the Ork Underground and after some complications, placed the Serpent Crown on the skull which caused a large spirit of a dragon to appear. The dragon spirit remembered his identity: Lord Keiga of Atlantis. He was a general during the ancient Atlantean civilization’s war with the Arisian civilization, based on Mars. The Arisians promised peace but eventually used their magic to kill all members of both civilizations. The spirit is sworn from allowing this to repeat itself and has been active because it picked up the signature of Arisian magic. It promised Team Adventure several boons, all associated with use of the crown.
