RTF is a global modification that replaces all towns in the game.

The Troglodytes were initially just a test mod with creatures, and I didn't expect it to be integrated into the mod so quickly. That's why the texts and heroes are old; I didn't know about the Obsidian and Onyx creatures at the time, I'll fix it later.

And there are also several other important details.
Firstly, it would be good if you changed the model and name of the Mage's Treasury, as the units inside are Dark Gnomes, but the building's style doesn't really fit those units. The same goes for the Gargoyle Repository.
Secondly, why does the Battle March ability only increase the speed of Pikemen? In the Mage faction, the Golem March increased the speed not only of regular Golems but also of Steel and Obsidian Golems. Please fix this oversight.
Thirdly, since Troglodytes are available from level 1, the specialization name "Miner" should be changed to "Troglodyte Commander" (or something similar, it's up to you).
Fourthly, don't you think that the Onyx Elementals are a bit weak compared to the Lava Elementals? They don't have many stats or abilities. Maybe you could add a magical resistance aura and regeneration to them?
But overall, I really like the Dark Gnomes and Elementals; the Faceless Ones and Battle Riders are especially cool.
And the Troglodytes look very good; they've turned out to be like Dungeon Lords (similar to those in Heroes of Might and Magic III).
