Scripts that are needed:
MoveHeroRealTime - the hero runs as soon as you approach him (must have movement points)
SetObjectOwner - makes a certain object belong to someone
OpenCircleFog - shows an area of the map from a specified point with a certain radius
OpenRegionFog - shows a selected region to a specific player
And what about just moving without doing anything else?
AddHeroCreatures - gives the selected hero the desired creatures

It should cover everything in the manual

WE ALSO NEED A FUNCTION
I NEED TO WRITE IT
