Luco Dryad
Pisces Rugonis' younger brother and Pefko's master. Luco dedicated his entire life to create a medicine capable to cure Rugonis' poison blood. When Rugonis died, Luco lost his entire will, but thanks to Pefko, he found a new meaning to live. One day, Pefko fell with a terrible illness, that even Luco couldn't heal. To save him, he sold his own soul to Thanatos, the god of death, turning himself in one of the 108 Specters of Hades. As Dryad Luco, he started to turn all the ill people that looked for a cure, in Skeleton Guardians to the Hades' army. It was only when Pisces Albafica, Rugonis' apprentice, started to investigate the island, that he was finally stopped, killed by the Crimson Thorn.
