What are the details for your request?
I'd like a Nether Tower build. Approx 32x32 blocks in size, up to about 128 blocks high. This is a request for a semi detailed interior and a functional/navigable tower that looks nice.

The intent is players tp to the top of the tower and fight/work their way down to the bottom. There should be a combination of levels and players drop/descend stairs/etc. to go lower. It is not important that they always be able to go back up.

There should be a combination of large rooms on a level for battle, as well as smaller rooms on other levels which they have to navigate through/find the way down to the next level.

I would like a nether theme, with nether-like interiors. Not all blocks need to be nether blocks. Not all rooms/levels need to be battles. Some exploration would be nice.

Since it can be up to 128 blocks tall, there can be about 10-20 levels to the tower, depending on how high the tower is and how high each floor/level is. Decorative and "battle" areas can be mixed with "puzzle" areas or small parkour areas.

I am open to ideas and input from the builder for the purpose for each area. I wouldn't mind a walk through/narration if you have a concept in mind.

Players should not have too much access to the outside of the tower (except for windows/vista areas I can block off with barriers) until the very bottom.

The tower should have an "interesting" shape and doesn't need to be constrained to 32x32 blocks wide at all points, straight, etc. The size is a rough estimate -- since it doesn't need to be huge. (This is not a full spawn, etc.). The tower cannot be more than 128 blocks hight.
