Atlantis: Milo's Return

Kida, now queen and married to Milo, who decided to stay in Atlantis, is using the Heart of Atlantis to restore the city's former glory. Milo's comrades and Preston Whitmore arrive in Atlantis; while their arrival is unexpected, the Atlanteans welcome their old friends back into the city. Unfortunately, they have come to inform them of a mysterious creature causing trouble on the surface. Kida suspects that the creature might be Atlantean, stirring mixed feelings about her father's decision to keep the crystal hidden. They arrive in Trondheim, Norway and discover that the mysterious problem is actually the creature known as the Kraken, which had been attacking shipping freighters and taking their cargo to a cliffside village. At first they presume it to be an ancient Atlantean war machine, but they soon learn that the town magistrate, Edgar Volgud, seems to be controlling the Kraken. Their next mystery is in the Southwestern United States, involving coyote spirits. They later find a hidden city in Arizona that contains Atlantean architecture, which Kida realizes is an abandoned Atlantean colony. A sly shop owner, Ashtin Carnaby, intends to pillage the place for its valuables, but the spirits then turn him into one of them. Returning home, the adventurers discover that one of Whitmore's old competitors, Erik Hellstrom, who went insane believing he was Odin, the Norse king of the gods, after a stock market crash sank his company, broke in at night and stole one of Whitmore's possessions, an ancient spear called the Gungnir. They track him down in the Nordic Mountains, where he presumes Milo to be the god Loki and Kida to be his long-lost daughter Brunhild. During these escapades, Kida comes into a greater understanding of just how powerful the crystal is, and that she must choose between hiding it and sharing it with the rest of mankind. Having retrieved the spear, Kida realizes her father was wrong to hide the crystal from mankind. She combines the Spear with the Heart and lifts Atlantis above the water, restoring the city's former glory.
