A quick search on Google brings the results "Satyr" of half-human, half-snake. Other people say "Naga". I've seen "naga" used before, so I'd go with that instead. If someone more knowledgeable can confirm or correct me, it'd be good, as I'm curious now.
I picked up For The King in a Humble Bundle sale, and one mechanic that stuck out to me was a physical change to the world map when finishing a side quest. That got me thinking about special map-effect rewards for certain side quests in my game.
