The most important thing here is to destroy the enemy Castle first, as you can then get a free resurrection and teleport. You can only pass through the garrison with upgraded units. It's funny, but it's true. For some reason, peasants are considered stronger than militia, so you won't be allowed through with them. There is only one truly difficult battle on this map (with the 51st dragon somewhere). But it can be won without 45 Paladins. So, if you gave it away for viewing, it's not a big deal. It doesn't give the hero any bonuses anyway. After talking to Wulfsten, you need to turn left from the Dwarven Castle and enter a one-way portal. Then, just follow the path of least resistance (i.e., don't kill anyone). Note that all the Order creatures standing in your way will gladly and freely join you. You don't need to look for them specifically; they will join you along the way. It's better not to touch the Wolves at first because there is a quest related to them, and it's not a minor one. Also, the script for the appearance of two more Wolf units there doesn't always work reliably. So, it's better to reach the Priests first, who will give you the quest. You will get the key in the tent in exchange for 5000 coins, 10 crystals, and 5 gems. That's about it.
