Let me tell a little about Michael. Of course all is still forming and the backstory not written yet, not even fully thought through.
He grew up in Constantinople as the eldest son of the falconer of a well respected local noble. He was fascinated by the birds surrounding his childhood at a very early age and his father taught him about his profession. He flew - just before the fall of the city - when he was around ten because of a very bad dream. None of his relatives would listen, so he was on his own, although not quite - the raven of his father came with him. Since then he avoided civilisation and was more with the birds of the mountain - and of course the raven.
He learned to survive, he learned to hunt with the birds and with the bow, he learned to speak to the birds. The raven gave him one of his feathers so he could even learn to fly with birds. Now birds twitter a new bird arrived...
In stats there will be Falconry, but more Animal Ken and Animal Handling. There will be hunt, survival and the bow, athletics (climbing) and awareness.
I am not too sure about the life goals and ethics - he had a long time on his own and would probably need some guidance in that regard.
I was under the impression that there was a) too much overlap with Ioannes and b) too much Creo vis to be needed by magi (and as a Saracen interacting with local mundanes only, ...)
I'll scrape that one.
Not sure how much I will contribute to that, sorry.
