@ Madness, could you point me to the reference? I can't find it!
Kellhus needs to take Sakarpus with minimal loses. The Chorae Hoard is second to one at Golgotterath (TTT Glossary)
I wonder how one acquires a Chorae Hoard? I guess the Nonmen ransacked the Ark after defeating the Inchoroi, shipped all of the chorae out, these things are not forbidden like they once were because the long war has demonstrated their usefulness--history, circumstance, the rise of humans and the fall of nonmen see many chorae fall into human hands.
After the Ark was sealed, there was no chorae getting out (assuming the aporetics did their work there) and I can't see the Man'gaecca handing them out as Halloween treats.
Could it be that Sakarpus was orignally founded by the nonmen as a chorae-holding facility?
EDIT: clarifications?
