Barbarian (Part 1)

Saleen brought Nailisi up into the air, nearly to a height of four hundred to five hundred meters before he stopped. He did not go any higher, and even though it was winter, dark clouds filled the north and it was snowing.

Saleen was afraid a winter storm would appear, although those were rare.

Mages had a saying – be careful of lightning when one flies too high. This was used to caution someone against setting their sights too high, but it had come from a mage's caution towards lightning.
