Did you take inspiration from some particular legend, piece of folklore or myth to write your island?
What are your main references?
I mostly used common tropes from Greek mythology as a broad inspiration (with Ovid and Homer as the main sources).
Olos is a rather straightforward example of Zeus travelling incognito and punishing hubris and those who do not respect the sacred laws of hospitality.
For Taras, I played a bit with the idea of tarantism, a phenomenon mostly associated with Southern Italy but common all over the Mediterranean; I added some more strictly ancient Greek elements with Dionysus and the Maenads, as well as the double role of music as both cause and cure for madness (Apollonian and Dionysian), and then I included some hints at what is generally considered to have been the actual cause of this phenomenon - harsh working conditions and stressful social pressure being felt particularly by women in agrarian societies.
The main inspirations for Temnon are Achilles's blind battle fury and his refusal to return Hector's body, as well as Aristaeus's role in involuntarily causing Eurydice's death.
Xerras is mainly a twist on the sacrifice of Andromeda to a sea monster (and the regular sacrifices to the Minotaur), with the added theme of the ancient Greeks' vision of civilisation vs barbarism.
