Strange things happening at a siege

That is often listed in the spell description. Many units are specifically not affected when inside a fort (e.g.: Send Horror), others are (I fire one, forget the name at the moment). So I am afraid the answer is: Depends. But most don't I think.

Another suggestion is to pillage, pillage, and pillage some more and maybe ritual in some Black Death or other mass-death of your elemental choice while you're at it. I'm still a rookie, so I'm not sure if the supplies in a keep are a fixed number which aren't affected by the population, but if they in fact are, then that's a great way to continue smoking him out. Even if fort supply -isn't- dependent on such, you can at least get it to the point where there's very little he can build anew in that province given the loss in resources and potentially start cutting into his upkeep money.

If this is the Last C'tis stronghold then build temples around and flood the area with preaching priests. That will reduce C'tis dominion to zero thereby killing the pretender and the nation.

I have noticed that Spies, at least, _do_ let you know what's in a Castle you are sieging. Also, I'm not sure if someone explicitly stated this, so I will:

In my experience, very rarely do computers defend their provinces with Castles. Your attack will kill their PD, but not any regular army in the province. Any units in the province will be inside the castle which you are sieging.

For your case, just do the numbers, and you'll see why you can't hurt the walls.

1400 units vs your ~800 or so castle damage. Not nearly enough. otoh, they won't be able to feed 1400 units nearly long enough. If you can handle that army sallying out to meet you, you can just wait them out. Or, as people have said, surround the place with temples, move in a bunch of priests, and preach them out!

I have experienced this twice now with the C'tis castle being the Last thing on the map not owned by me. The dominion tricks sounds a good idea but starvation takes a long long time if indeed has any effect. The C'tis fortress had been sieged nearly the whole game, first by Jotenheim AI and later by me (around a 100 turns I think). The earth spell did do damage every turn but that was apperently repaired before the troops kicked in. I used the Ulm siege commanders and troops to open it up but still needed a lot of troops and time. Subsequent storming was also unsuccesfull for a couple of times (and resulted in a completely restord fort with 1400 troops)before I finally broke them.
