Martha

Madalena is from Lofty Peak, descended from the keepers of the portal to Nadiria. During a visit, King Pankraz of Gotha met and fell in love with her, and they married. However, shortly after their son was born, she was abducted by the forces of Nadiria due to her heritage, as Grandmaster Nimzo was trying to infiltrate the world. Pankraz traveled the world with his young son in tow, searching for the legendary hero and the Zenithian gear to aid him in rescuing Madalena. By the time their son was only six, he had only managed to recover the Zenithian Sword.
