Discussion of the Necropolis faction.

regarding vampires, yes, but ghouls are quite similar.

Ghouls are European undead, with the prototype being the Arabic type of malevolent jinn, Ghoul (in Russian, they are written the same, but in English, the spelling of the words differs; first, they are translated as "Ghouls" and "Vampires," and the latter are still called Ghouls).

well, "ghost" - something has changed, it's still in Russian. The intelligent ones understood what I was talking about, namely that in English, "specter" and "ghost" are different words, but in Russian, both words are translated as "ghost."

It needs to be clarified properly because instead of the English pronunciation, you used a Russian synonym. In the end, there are three options (off the top of my head) for these creatures for translators:
1. Ghost
2. Specter
3. Spirit
