Far in the north, a tribe of frostwolves have made their home.
The wolves have a rite of passage where one has to prove themselves by surviving
the fiery breath of a dragon, relying on their frost magic alone.
...After which they also have to make it back to their tribe.

And well... if the dragon happens to be having an off-day, it's gonna make the latter quite a bit harder.
Most days he seems amused by it, though. He's a pretty cool guy.
