Moving on to another topic, I've always been fascinated by TLS' major powers. Obviously power is hard to quantify as tower magic is involved, but I've assembled a motley rank:
Obvious. They're probably roughly equal, but I'm putting Hester ahead as the one "battle" they fought, Hester won (granted it was in her turf, but still ... she cast out the Anak AND Wendis). Hester in particular sealed every. single. incubus king. Except the weird ones.
Thanks to the Incubus Prison, Simon has absorbed all the shards inside him (including at least 2 major shards from the IK and Lustlord, almost a full one from the Fucklord, and a bunch of small ones).
Everyone is scared shitless of her. Wendis is presumably really, really hard to kill as the Anak didn't even bother trying to kill her when she was weak as it would take way too much effort. Recent achievements include curb-stomping Nyst and Tanurak simultaneously. Also, at the start of chapter 4 when Sabitha tried to bait the Fucklord into facing Wendis (and failed), Xestris seemed to imply that (weak, bodiless) Wendis would win.
Is the sole reason Hester/Anak hasn't won. Banished them both to a labyrinth at the cost of his own life. Is also able to hide himself from the Anak.
Outright beat Esthera in a 1v1 duel, and still have enough energy to fend off the DK and co. Required Esthera to weaken him, Simon to bind him, Xestris to seal his regen, and a strike team to finally kill him.
Could singlehandedly take down parts of the LoB's fleet. Strong enough to spook LoB and pressurize the IK. Bent the shard to her will via the tower and is mentioned as having tower-level defences by the Anak. Record a bit stained by her loss to Lustlord.
Beat Sabitha, obviously. Is definitely weaker than Esthera, but has beaten Antiala/King Kanfuor.
Constructs wards strong enough to fend off Tanurak. Insta-killed the Lord of Blood, but was left hapless afterwards.
Great Sage of Ghenalon
His entire record is kicking Tanurak's ass, and then getting his ass handed over to him by the Anak. Is said to be powerful by the latter.
The Fucklord thinks he can beat her if the DK's not around, but then again he's the Fucklord. Track record isn't great as she hasn't really done anything direct.
Doesn't have much raw power, but is incredibly slick. Defeats Ulrissa.
Talks a lot about balance and neutrality and stuff. The one time she actually tried to fight, she got her ass handed over to her by Tanurak. Also failed to expel Simon when he was still beginning to explore the tower.
Props for pulling the biggest con of all time. He's weak enough that the Anak could discern him, and also weak enough that the Fucklord could kill him.
Despite having no army, was able to fight on par with the LoB and his airships as well as Simon and his (admittedly rather small as the Incubus War was sudden and so he couldn't mobilize) fleet and ground troops. Eventually managed to escape Wendis' grasp if not weakened enough.
Lord of Blood/Fuzkao
Doesn't seem to have much in personal power.
-Goddesses that are on theory major powers but haven't fought directly like Ivala, Tertia
-Lilith and Mestan; just not enough info
-Minor IKs with no achievement or significance whatsoever
-Simon's harem members
