School of Gemcraft

In the highest of studies, there are magi that take their craft to more intricate levels. Those whom study magic in other places not fit in standard schools of magic. But always present in it. The study of gems is the appreciation of their value and symbolism. It is recognizing their place in the world and how they all connect and weave into the tapestry of magic as a whole.

“You can’t always trust the world to come in and make things right. You can’t always trust others to come by and do things right the first time. Or the second time. Or ever really.”
“When it comes to things that truly matter to you. You have to be the one that decides you’ll do it right, because you don’t think anyone else can. Otherwise you’re just a coward, right?” ~ Isabelle Galatea
