Skull of Shadows (SoS) is a Polish mod that replaces all the factions.

In Necropolis, the architecture consists of pyramids with extensions and towers in the style of Chaos from Warhammer. Let's skip the towers, and the Necropolis from Heroes 6 would be a good fit. But initially, I'll leave the city's visual style as it is.

Maybe someone can help me with a video? My gnome disappears not as I want (he disappears immediately when the required dialogue is played, although he is set to disappear after 6 seconds and the casting animation on the first second)!
