This simply makes flame atronachs taller by editing their height in the race settings, taller than an altmer but shorter than a frost atronach. The mod file size is very small only 1.58 KB as it's an extremely simple mod that only changes that one thing. I made this in part because I think I remembered flame atronachs being taller in Morrowind before the Devs decided to shrink them a bit in the next games (if I remember right), and I think it makes flame atronachs look much more powerful this way, regardless whatever the case I wanted flame atronachs to be a little bit bigger than they are in vanilla, and perhaps some other people feel the same so I made this mod.

It's still a small enough change that it almost certainly won't cause navmesh or collision problems.
