1. Slow and Haste affect initiative, not movement range.
2. I named Astral Gates, summoning creatures, and city portals this way.
3. In Heroes of Might and Magic III½, there are some caves, towers, ruins, etc., where you can't get a quest, but there's a mini-quest: you go in, and there's something like "turn left or right," and then they might attack you, etc.
4. I understood correctly.
5. Are all the cities in Heroes of Might and Magic V Haven? I don't know if Conflux contradicts that. Swamp isn't Haven; it might be in the game. But Cove and Bastion... I think it would be great to play as them in Heroes of Might and Magic V.
