Yeah Kellhus did a lot more than Conquer lands and fight wars in the 20 years between the books. I bet be plumbed the depths of many secrets, including what was left by his father. We might not know Moenghus Sr. fate, but Kellhus certainly does. Or, at least, he knows if he survived his encounter with Cnaiur and the skin-spies.
I've wondered about this. Not sure where this comment belongs, but what the hell. Kel and sons wear nimil armor, stuff he must have found in dear old dad's former abode. I used to think he may have struck some kind of clandestine treaty with some nonmen, but it's more likely he found the stuff in the mansion. Anyway, in TWLW, Fanayal is described as wearing nimil chain, as well. Stuff must be just laying around for anyone to use. Unless... Fanayal is allied with Kellhus. Or he's a mole, like the priestess of Yatwer was. Same thing either way: all part of TTT and Kel's manipulations. More useless speculation.
I like this, Somnambulist.
Wilshire and I have talked a couple times of Kellhus' Personal Adventures since the First Holy War. Definitely, had access to all the available written works of his empire. Also, definitely explored the Southern Nonmen Mansions - including possibly Cil-Aujas! It could easily have served as Kellhus' training ground, fortress of solitude

. And he might even have possibly brought down the roof in the Mortuarium. Wow - MG is influencing me already.
That's another thing. The Serwe skin-spy would have either set those captive ones free or killed them. He/she would not have left them hanging around like they were, Imo. Maybe Moe had others penned elsewhere...
They could definitely identify if there were others in the Mansion. Smells, etc.

Thats an interesting detail. Was nimil worn by anyone before Kellhus was AE? It is possible that Fanayal simply found his own set after becoming aware of the Mansion outside Shimeh. Though it is equally likely, if not more so, that Kellhus furnished all of his Generals (or his Kahit [I can never spell that word]) so as to provide them with a bit of extra protection when he wasn't around.
Kahiht

So we've highlighted an interesting either/or. Either Nimil is readily accessible (and remember according to Cinial'jin's Atrocity Tale, it seems Erractic are normally walking around and crossing foul with human populations) or Kellhus controls all the Nimil trade in the New Empire...
Fanayal is an agent against or an agent of?
Can't rule out the possibility of Kellhus raiding other abandoned mansions.
Bakker is a D&D gamer - Kellhus definitely raided him some Earwa. Lmao. I'd like to see Kellhus' stats at the end of the First Holy War as compared to the start of TJE.
