Diancastra

Diancastra was a deity in the giant pantheon, the Ordning. She was a minor trickster goddess, unlike her older sisters Hiatea and Iallanis.
She was fathered by Annam All-Father himself, but her mother is unknown, speculated to be a cloud or storm giant. Unlike her sister Hiatea, she did not earn her divinity through feats of strength, but rather by acts of wit and wile. She accomplished this by stealing a magical necklace from Umberlee the Wavemother, disguising herself as a kuo-toa and sneaking into the Sea Queen's palace.
After her theft from the Sea Queen, she soon announced herself to Annam right before his departure from Ovatria. Citing her sister as Hiatea as a reason why she should be given divine status as well, Annam issued her one task to prove it: to circle the earth in an hour or less, knowing she could not accomplish this task (lacking great powers and items). She went into Stronmaus's library, took one of his atlases, and tore out a page illustrating the world (much to Stronmaus' displeasure). She drew a circle around the world, and presented it towards the All-Father. In a fit of humor, Annam made her a demi-goddess, trusting her to leave some joy in the face of his departure through her acts.

Divine Symbols & Sigils

Diancastra was famously a master shapeshifter, but regardless of her form would always have a sea-green streak along her left side. According to legend, this was a curse put upon her after being caught attempting to steal the pearly crown of the Tritons before she was a demi-god. Priests of her faith will often use hair dye and tattoos to emulate this mark.
