Steel Beasts: Panzers in a Fantasy World (Prolonged Hiatus)

A King Tiger. Two Panthers. And a half track with a squad of engineers. How do they fit into a fantasy world?

Hopefully a non-generic isekai story involving WW2 Germans, their tanks, and fantasy elements such as magic, fantasy races like elves, and stuff from my own imagination. Still thinking of overall plot. Sorry if you wanted a fully fleshed out story.

Note: Other than for character background, no real world ideologies are involved/supported/encouraged. Any likeness to real life people are non-intentional and purely coincidental.
