Entering a starfort's powder magazine is often an almost holy experience. A powder magazine is usually a completely separate entity from the fort with which it is associated, was built more stoutly, and great pains were taken to ensure the security and careful handling of its contents.

In the case of Fort Niagara's powder magazine, when I first stepped inside from the rapidly brightening day, it seemed as though a heavenly cloud was floating just under the structure's roof. As my eyes adjusted to the dark, I saw what you can see, that the upper part of the magazine's walls and ceiling are lighter-colored masonry, while the lower walls are lined with wood to lessen the chance of rogue sparks leaping into existence and instantly blotting out anyone so unfortunate as to be existing nearby.
