The city of Ilata.

Racial ability - "Invocation of Silat"
1st option: school of air magic, with various spells.
2nd option: Silat's blessing/curse - 50/50 chance that either your army is blessed or the enemy army is cursed. Costs resources/artifacts/mana.

Special ability - embodiment of Silat - the hero spends all mana and summons a powerful spirit (very, very strong). Possible once every two weeks/month.

Simple abilities:
1. Whirlwind - the hero summons a hurricane - a neutral creature that occupies four cells. It appears in a random location and captures any unit that enters it, but only one. It holds it and drains its life. The unit can be attacked with magic and arrows, but the damage will be less. After a couple of turns - depending on the strength of the creature - the hurricane throws it out and wanders around the battlefield until the end of the battle, becoming weaker with each turn. When capturing a unit, it can be freed with the spell "Remove Curse".
2. Storm - when used, randomly scatters creatures across the battlefield, dealing small damage. Does not work during a siege.
3. Favorable Wind - used in battle/on the global map:
in battle - increases the damage from ranged attacks, some spells, and speeds up flying creatures. Slows down enemy units, weakens the damage from arrows and spells (partially).
on the map - increases the movement range on the sea.

All abilities require mana expenditure.
