I'll teach you how to make this fine mail armor, but only if you agree to certain conditions.$B$BBy choosing this path, you agree never to learn elemental or tribal leatherworking; there is only room for one of the three at the apex of the craft.  Furthermore, I'll need some samples of your best work involving scorpid armor.  Finally, I'll need proof of your ability to acquire the staple of the trade: scales of the dragonkin.
