Posts from Air level of the map.

Alright, I guess you can't be convinced. I initially thought you'd talk about UFOs, but you're talking about spirits...

At the same time, Jhel attacked the silver cities and, using a secret magical portal, managed to reach the heavens and establish an empire of air elves there.

The idea of spirits actually arose spontaneously. Moreover, the world of spirits has existed with people since time immemorial. And there should be no scientific and technological progress in the world of Might and Magic by definition. And excessive embellishments sometimes do not improve, but worsen the game (for example, In the Wake of Gods). The game should be intuitively understandable and logical, i.e., new features should not contradict the main game (for example, like Forge). Otherwise, it will already be a different game.

Who is Jel?

Jelu is an elven hero, and quite a famous one – he has done a lot, even destroyed the world... but he is a good hero.

In general, on the aerial level, you can create an arena for battles between the ghosts of fallen heroes, as well as a place for moving ordinary warriors on airships or on foot. And one more thing: the ghosts of fallen warriors cannot interact with the living in any way.

That's also a good idea, but it could also be applied to sieges of ground castles.

For example, the first arena could be the siege, the second the inner part, and the third the castle hall.

Let's say, during a siege at the castle walls, when the walls and gates are breached, the defending army has the opportunity to retreat into the city limits. By choosing to retreat, the besieged army falls back to the second line of defense – let's say, behind barricades – and the battle action takes place in the narrow city streets. In an even worse situation, they can retreat to the last line of defense – the castle hall, separated from the city by strong walls and gates.

Something like that, but it would be better to introduce a second garrison. The first will fight at the walls, the second in the streets, and the third in the castle hall.
