-look, it's a bird
-no, it's a man
-no it's... what are you finelly?
-shiip shiip

Himself don't know. Was it a bird transform in a magical creatur by magic? a mage trying a metamorphose? a fusion with a bird and a mage? Very confusing when you wake up with no memorie exept some spell and how to make a nest...
whatever, is now a great mage, and no body contest it since half of the concil had some vengeful dropping on their hat when they wake up.
