I was kinda confused about little Kel and his ability to mess with WLW powers; had to made a soothing theory.
1) We knows gods are blind to certain things: No-God existence, Consult plans etc. There is guess that Tekne makes borders of gods' blindspot and, more specifically, it's distinctive product -- intelligence, which lacks "proper" concience or "enough" complexity. Correct me if I wrong here, please.
2) Kelmomas mother had a very close contact with Tekne, I mean than identity theft of Kellhus by Aurang.
3) Being of Kellhus children, Kel is a broken dunyain thing, which by itself has a certain taste of near-Tekne experience.
4) His POVs are all about personality problems, about rule "one head, one voice" being constantly violated.
So at least I reckon Kelmomas is somehow hidden from Gods eyesight thanks to a combination of few factors listed above. At most -- his metaphysical position is symmetricaly opposed to WLW. Either way, boy can fuck up other's plans, especially if they are godly.
PS That can be a possible answer to a question why Kellhus didn't drowned him in the first place.
PPS Dunno now, if Ajokli is an actual trickster god or it's a placeholder name for a sum of gods' debility manifested in the world.
PPPS What have I done. -.-
