The Santelmo is a creature of Philippine mythology. The term santelmo is the shortened form of St. Elmo's fire, a strange weather phenomenon named after Erasmus of Formia, the patron saint of sailors. This phenomenon has long served as an omen of heavenly intervention to sailors and involves a luminous plasma created by coronal discharge from a pointed object in an atmospheric electric field. Sailors see this occur on their ships during a storm at sea; however, they are divided to the type of omen it is. For some it is an omen of bad luck and stormy weather due to compass interference, for others it is a omen of good luck.
St. Elmo's fires have ranged from a ghostly dancing flame to natural fireworks. It usually is of a blue or bluish-white color attached to fixed, grounded conductors, and has a lifetime of minutes. The flame is heatless and non-consuming, occasionally accompanied by a hissing sound. These latter properties prove the myths of spiritual presence.
A rather large, bluish, evil spirit that resembles a skeletal human torso with an ectoplasmic tail. They appear in infinite numbers in oceanic areas, announcing their presence with a nostalgic sigh. They enter from either side of the screen and change direction once to aim toward Shanoa, continuing their path until they leave.
