Ever since I've become Durin's Patron, he's opened quite a few spreadsheets to me as a reward, here is what I have found out!
The Imperial Trust is just barely able to tolerate the Quartok, as a whole. -1 out of 10. They like Avernites (8/10) just a little more than Avernites like them (7/10).
The name of the Ork in charge of a tier 6 Waagh is called "Trinity of Gods". Given that he would be at a minimum a Transcendent Combatant, with an extra +3,200 combat bonus on top of that, I am confident to say that calling Beast^2 a "God" is in no way, shape, or form an exaggeration.
500 billion Orks in one system is a level 2 Waagh. If 166.66 Billion Orks are all fighting together, then that counts as a T2 Waagh. You only need ~4 trillion Orks all fighting under the same Warlord in a system in order for it to qualifiy as a T3 Waaagh.
Durin is keeping track of our noteworthy "achievements", one of which is called "The Ends Justify...". 3 guesses what it is for.
About one in every 18 million Avernites is born a psyker. Any Avernite Beta has better than 50/50 odds of staying loyal! That's better than their expected pass rate!
The only named OOC Dragon's Nest World is Menagroth, their capital. You know, no one has every really gone into Rotbart's past as a lifelong Administratum Clerk. He was 90 when he became the Governor of Avernus. You could easily put his homeworld, Gallium III (civilised world), inside the Dragon's Nest. We could even visit our old home for some good old character development.
