Armageddon's Blade
In the original unreleased Armageddon's Blade campaign, the artifact was supposed to be found by Gelu in one of the Ancients' vaults, the Varn 1904 Vault, destroying the Heavenly Forge and any evidence of the Forge's existence with it. This is in fact hinted by the artifact's message when finding it on the adventure map, which wasn't changed and remained the same as the old one.
Goblin
In the lore itself, the goblins (and hobgoblins) are aliens. Their blood is also green. In one of the Armageddon's Blade teasers, the goblins were shown having bows in their hands. The reason for that is because the teaser animations were already done and were supposed to show a Forge goblin instead, which used pistols. However, due to fan backlash, they had to change the Forge creatures into "regular" creatures, and so the teaser became somewhat off-topic with ranged Goblins, a Minotaur and an Ogre guarding the so-called Varn 1904 Vault where the Armageddon's Blade was kept. Their Forge equivalent was going to be called Grunt and its upgrade Foot Soldier, being a level 1 troop.
Minotaur
In one of the Armageddon's Blade teasers, the Minotaur was shown together with an electricity-shooting Ogre and ranged Goblins. The cause for this was because the teaser was supposed to include the Forge version of these creatures, the Minotaur bearing a jetpack on his back and the Ogre a rocket launcher or bazooka. However, due to fan backlash, they had to change the Forge creatures into "regular" creatures, and so the teaser became somewhat off-topic with ranged Goblins, a Minotaur and an Ogre guarding the so-called Varn 1904 Vault where the Armageddon's Blade was kept. Their Forge equivalent was going to be called Jump Soldier and the upgrade Jump Trooper, level 5 troops.
Naga
The Forge equivalent of the Naga and Naga Queen, a level 6 Naga troop whose lower half was a tank and the upper part naked, was going to be called Tank and its upgrade Heavy Tank. It was also supposed to cost special resources and most probably bear stats similar or close to a level 7.
Ogre
In one of the Armageddon's Blade teasers, the Ogre was shown shooting a beam of energy from his club towards a Dendroid. The reason for that is because the teaser animations were already done and were supposed to show a Stinger or Bruiser instead, the Forge version of the Ogre, which bore a rocket launcher or Bazooka. However, due to fan backlash, they had to change the Forge creatures into "regular" creatures, and so the teaser became somewhat off-topic with ranged Goblins, a Minotaur and an Ogre guarding the so-called Varn 1904 Vault where the Armageddon's Blade was kept. The Ogre in one of the Armageddon's Blade wallpapers is in fact a Stinger or Bruiser (the Forge level 4 troop), disarmed and defeated by Gelu. You can also see the laser-pointer of one of them in a wallpaper featuring Mutare in dragon-form.
Rust Dragons
In the campaign's prologue, a Rust Dragon sitting on something that looks like a mine can be seen. However, that is not the entrance to a mine, but to an Ancients' vault, the Varn 1904 Vault, where the Armageddon's Blade was originally supposed to be found in the original Armageddon's Blade campaign, which would have featured the Forge as the opposing faction.
Zombie
As a "gift" from the Necromancers, the Forge was able to create its own zombie troops, the level 2 Cyber-deads and Cyber-zombies. The base unit had only a single regular chainsaw instead of a hand, while the upgrade was going to have 2 circular saws instead of both arms.
