I'm struggling. I love my campaign, I love my group, but I've had so much happen in the last year that it's become a marathon sprint to the finish and I am super burnt out both as a DM and in life but I refuse to quit when we're two sessions from the end. I won't get into all the things that have burnt me out along the way because I don't fault my players, but it's been a lot.

The final scene is well planned but to get there the players need to summit an 850m tall tower. (Don't ask). The tower is in an urban area and extremely closed off from the city outside. By the time they reach the top, not only will the city have been destroyed--the plane will have been. Sort of. It's complicated.
The tower is used as the premier wizarding college for every school, including Necromancy, but currently every member of the Council of Wizards is missing for B Plot reasons that the party didn't explore so the school was suddenly shut down.
However, the tower is older than the city and was built as a wartime effort against a planar-magic wielding dominion so the upper levels will be more dedicated to that, including a device that can imbue a departed soul into an inanimate object, and/or possibly a single-use mechanism of full resurrection. Maybe. Planar bullshit.
Big bad is a primal entity of destruction and is actively attempting to destroy the city, the world, the planes, and the spaces between the planes. Not important.

What I'm asking for
Content ideas. Not looking for people to do my planning for me, just help me get started on puzzle or progression-based content for this magic tower. I can't even wrap my head around things to happen or do as they climb and I really don't want to go to AI for it for obvious reasons.
I've been mulling this over for two weeks and I don't have a single event or spark to show for it. idk, maybe this is too big of an ask for here. If that's the case, I am sorry.
