Oh-oh-oh! Hooray! I was starting to worry that something might have happened to you! :D Let's get started... :) As far as I know (though I might be wrong), the word "gargoyle" doesn't have different forms for masculine and feminine genders.

Once, humans and bats were crossed.

But what about stone gargoyles? Who was crossed with whom?

This species was characterized by its ferocity, Dark magic, and limited vampirism, which was most evident in Gargoyle heroes.

Where did they get their Dark magic from? And how does their "vampirism" manifest? Do all troops gain vampirism? That's wonderful...

In the year 467, a rebellion against the Mages took place.

Why are your "races" always attacking the mages? There shouldn't have been much left of them by that time...

not only to escape, but also to save many orcs.

Orcs?.......

hiding them in the wastelands of Ranaan.

The wastelands of Ranaan?..... o_O

The Gargolans settle in the Igg-Shail Mountains.

Heh... am I wrong, or is Igg-Shail an underground land? I don't remember hearing anything about mountains... I'll edit this later.
