These might be words that will inspire you:
Mystery, intrigue, detective work, adventure, story tale, fun, hidden,
playful, saga, quests
Our demographics tend to skew a little bit to females around 24-45, but we don't want to turn off the guys either.
The word "Fable" has an old school storytelling component to it (you can imagine a book) and "Labs" is sort of the modern way we produce these.... thus we're open to a range of ideas from classic to modern looks... maybe even blended together somehow.
FableLabs is one word but the 2 words should be styled or colored so that the separation is clear that it's 2 words put together.
