I really liked the premise of the submission, being transported to a fort that you have to defend while a ritual is being completed is very cool.
To make this better, I'd suggest being more concise with your writing.

Thanks, defensive scenarios are really underrated.
I agree the first few paragraphs can appear a little wordy, but once you get into it, I feel the main body of the adventure (the fort, its 9 rooms and the 14+ events of the siege, timeline and spells) is pretty concise. It's all very playable and I thought about what did/didn't need to be explained and described. Maybe I was a little ambitious with how much to include which makes the entry seem a little full. If I could spread the entry over another page, you'd see it.
