Well, by anything, they mean 'Anything that seems alright for a fantasy setting that isn't too modern'. For instance, there are people with immortals and there are people with ordinary humans, and there are many points in between. The cannon and the pistol is a recent invention in one country, so you can't make anything too advanced. I have an innovator who is starting to create new things, but it is - for instance - a grappler gun built from a carefully-built wheel-lock pistol. I have this innovator, but also...
A Bakeneko (Ghost Cat Demon Magus Thing)
A Crazy Shopkeeper
A Goblin Rogue
A Kind and Generous Fighter-For-Hire
A Guy who Descends a Dhampyr
A Deadly Vampire Warlord
A Laid-Back Demon
A Ferret with Metal Magic
A Vorpal Rabbit
A Young Necromancer
And a Thunder Kitsune (Fox Demon/Spirit)
Just as some examples of the things that can show up here.
