I don't really have many ideas apart from the magic system. i do know that the book will be set in a city that looks and feels like old london. exsept it kind of glows with a golden light. this golden light attracts winds and repels blights. if you bonded with a wind you can use the light to form small objects like a cup or a plate or a knife.
i would love to see some maps and hear any of your ideas @The Sibling.
