The Guild of Self-Important Engineers is really important. They decide what is fact and fiction. They don’t need anything as base as evidence, however. No, they just know what is true and what is false. They were inducted into the guild by other guild members because they published papers that agreed with the guild, and they give their stamp of approval only to engineers who also agree with the guild. See how that works? Totally not biased.
The Arrogant Elf is the chief engineer. He is often accompanied outside the guild by his Blood Elf…“friend”.
