Yale didn't have any doubt that the cloak was crafted by someone like Tofesh, but if that person had sold his crafting, he would have been quite famous, and that wasn't the case.
Tofesh wasn't very famous, but for someone who had yet to become a Law Master, his works were of too high quality, so it wasn't difficult to find some information about him.
On the other hand, there had never been someone similar to him in making clothes like that cloak.
The person who crafted that cloak should have done it to use it himself or to give it to his descendants.
Yale guessed that probably the person who gave the legacy to Gerken was one of that person descendants, or he was a friend of those descendants.
That cloak had protection, only people acknowledged by the previous owner could use it.
