Can I set up my general (Lord-Arcanum therefore enabling Sequitors-Battleline) in reserve, set up my Sequitors (counting as battle line) on the battlefield, and if so is there just no general on the battlefield until the Lord-Arcanum arrives or is another hero general, and if so does the army list's general, the Lord-Arcanum, become general upon arrival? And if there was no hero set up before the battle begins, does the first hero arriving become general?
