Angel of storms

Fantasy. Tyen trains students in the ways of magic, but his teaching may soon be outlawed. Rumour has it that the formidable ruler of all worlds, long believed to be dead, is back and is harshly enforcing his old laws - including the one forbidding schools of magic. As teachers and pupils flee, Tyen is left with no home and no purpose - except to fulfil the promise he made to Vella, the sorcerer imprisoned in a book.
