I've been wanting to test a scenario like this.

Current role at the guild

He came up through academia, with three published papers before he turned twenty one, and Aegis hired him straight out of his post-doc. He runs the numbers behind crystal refining, making each batch yield more usable energy than the last, and his models are why Aegis's supply chain has stayed a step ahead of every competitor for six straight quarters.

Why they would switch guild

He wants a new challenge. Yours presents an interesting scenario. He'd like to see how it plays out.
