As for the wall spells unless Permanency is cast upon them they are only temporary. It was decided to move to defend the second wall. The frontal defense of the fortress is like a funnel or V where the outer most wall has the most space to defend. So with the outer wall pretty much open in a lot of spots the good guys pulled back.
You are indeed correct I thought it was like normal walls but both it and Wall of Iron are permanent.
Your a 13th Lvl Mage so the wall would be 3.25 inches thick and 260 feet in service area. Hmmm that causes a slight problem, in creating the wall I don't think you could create battlements for the troops to defend from as it says a slab of stone. On top of that I believe the Fortress walls are much higher and thicker then that. Gotta check the fortress walls specs to be sure but I think the height difference between the spells would not be the same.
Either way your walls would have given the defenders the ability to retreat with those walls as cover.
The spell would produce 260 feet squared of surface area. According to the spell you can add crenalations, battlements etc. And it's possible to layer the spell with multiple casting (i.e. one behind the other, or one on top of the other). Sirene could have cast it 5 times, so it's possible that it could be fairly sturdy.
That said, I still don't think it would last for long. Stone walls aren't great at stopping magic...
Gina you are correct in your summation of Wall of Stone. Your right you could have repaired a good portion of it in two days time. Though not as strong as the original wall was still would have held up quite well. However to not have to rewrite my whole post I’ll just go along with you and say magic eventually brought it down enough to have to abandon it.
It seems at the very least two of us will attempt to find the wolf... A simple yes or no to this question, 'Is the wolf found or not?'
If it is we will role play as such. If for all the chaos it would be less likely we can get to the recovery of the wolf then we will role play it to that end as well. Perhaps searching from the top of the wall to no avail.
A simple yes or no and it gives us a little role play for a week or two at the very least.
