[@ArkmageddonCat]: Okay a couple issues here:

Rune etching is more how magic is imbued into weapons, or you're a mage and you do it directly but that's a more complex process. There's also a pretty low chance of finding an elven smith in Thaln, and given the timescale elves operate on finding one that would believe you ready to leave their tutelage and become a knight on top of it after only a few years would be even rarer.

Finally, he should have something under his belt that gave a good reason for the Roses to consider accepting him into the order.
