That's quite an assertion.
Apparently one who didn't see the elves send a team which got ground under Redcloak's foot. Or possibly one very invested in the concept that the Order isn't--irrespective of how competent they are in using their power--very powerful by the standards of the world where they exist.(...indeed one wonders why the elves, if appraised of AC's fall, would not be taking action even now.
Indeed, the gods are unable to act against each other for fear of causing another free-for-all like the one which created the Snarl to begin with. Xykon, whether he knows it or not (and he doesn't), is one of the Dark One's champions in this matter, therefore the other gods will only act against him through mortal champions of their own.However, let's say Durkon telephones Thor with a warning. Were Thor a rational human/dwarf/elf/goblin, Thor would squash Xykon promptly and easily. But that's not how the gods work.
...That does not appear to be the reason you are claiming exists for Thor not to smash Xykon, however.
Perhaps it's related to the way the only indication we have that Vaarsuvius didn't eclipse his/her master when s/he cast his/her first sixth-level spell, is the implied-and-not-even-actually-given word of three archfiends.Why V doesn't contact V's master is a bigger mystery, but perhaps it's related to Kay's Observation:Spoiler"There's always an Arquillian Battle Cruiser, or a Corillian Death Ray, or an intergalactic plague that is about to wipe out all life on this miserable little planet, and the only way these people can get on with their happy lives is that they DO NOT KNOW ABOUT IT!
