A highly enjoyable read. Ron is done well, not so much malicious as self absorbed and thoughtless. They helped Merlin, does that mean he joined and is still alive? Possibly this Brother Cobra?

I haven't decided about Merlin yet. He might be in the story further along. Cobra we'll meet right after halloween -- one of the first animgi. Jason is a Bronze-age warrior, think Hector. Cobra is a loner, a powerful Mage who is interested in the world but not usually in people. Cobra is one of the few brother able to intimidate Jason. Osiris is the only being able to command Cobra.
They all like Harry.
Snape had best tread very very carefully.
