You start out with six level 20+ heroes, and nothing on
the map will be able to stop an army like that. Since this is the only
campaign where you get so many high level heroes, you might want to keep
them together, just for the novelty. But it's probably best to put the
named heroes into one army and the two random heroes into another
army. Then the named heroes can do most
the work while the random
heroes pick up
Once you decide how to group your heroes together, head east. You
should find two quest gates and a tree of knowledge. The first quest
gate is optional. If you send a hero with three vials of acid to it,
you'll be able to pass and visit a couple skill buildings. The second
gate leads to one of the three neutral towns on the map. It'll let you
pass if you have Desette and Kentaine in your army. Then, once you
take a few steps past the gate, the neutral town will convert to your
side. (The other two neutral towns will convert to your side on their
own, several days into the scenario.) The tree of knowledge requires
gems, so hit that as soon as you can afford the price.
Once you clear out the area near your first town (being sure to visit it, so
you can set a governor and get Desette more spells), send your main army
back to the starting point while your secondary army uses the portal. The portal connects the three towns that will eventually be yours, and your
secondary army should be powerful enough to clear the areas around the towns
and flag the nearby resource buildings.
Your main army should then head south into a fenced-in area. There
you'll find an optional quest hut (defeat the Blue-flagged peasants to the
west for eight healing potions), lots of troop buildings (peasants,
ballistae, monks), and a blacksmith. Be sure to visit the blacksmith
to get your heroes some equipment.
Then head south again, and finish clearing out the areas surrounding your
three towns. You'll end up controlling several resource buildings, and
you should even find another tree of knowledge. Meanwhile, continue to
build up your towns, and go with angels at each one. You should be
able to afford them in this scenario, although it might take a while to
build all the altars.
From here on out you'll have to do battle with the three computer players,
but notice that all attacks on your domain have to go through your southern
town. So build that town up and keep troops there, just in case the
computer decides to attack. (It probably won't.)
You can do as much conquest as you want. Teal is located to the
southwest, and it is convenient because your southern town blocks access to
that area as well. So if you take it, your southern town will still be
in a position protect all of your other towns. And to get to Teal, you
only have to kill a large stack of hydras. Since hydras are big,
slow-moving melee units, they shouldn't present a problem.
Orange is located to the east. The path there is guarded by a large
stack of thunderbirds, and thunderbirds can be a problem. But you have
to get by the thunderbirds since the path they're blocking also leads to Red
(Warton's color). The best way to deal with them is to cast mass slow
and then pick them off before they can get to you. But if you don't
have mass slow, try to let your heroes take the brunt of the damage, and
keep your angels mostly out of the way.
After you defeat (or simply pass by) Orange's first town, you should notice
the entrance to Red's lands. Red is blocked by a quest gate that only
allows an army with Lysander to pass, so Red can't go anywhere or attack any
of your towns. So feel free to defeat Orange's second town if you
want, just to be thorough. Then head for Red.
When you capture Red's town, you'll find out that Worton has escaped. You'll find him to the east, past another quest gate. But the gate
will only let Lysander pass, so make sure he has all the good equipment,
plus assorted potions, and send him through. You'll find Worton plus
some bandits on the other side. If you've been developing Lysander's
combat skills, this should be an easy battle. You might even be able
to kill Worton before he gets to you. Otherwise, just use potions of
immortality and healing if you need them, and grind the battle out. Once Worton dies, the scenario (and campaign) will end.
