I am thinking of writing a walkthrough, but unfortunately the length of this campaign, and my lack of preparation or note taking, has really made this impossible. There are way too many important battles and artifacts and crucial save points.
Am very pleased to say that I defeated Queen Marlindra, the boss supposed to be practically impossible to kill on the field. Mana cost about 1000. The losses are merely clones. After 11 tries, I found that Queen Marlindra never approaches my castle, so I had to go out and fight her.

I had the aid of the 250 extra Titans from the Gold Dragon seer. (The 2 Gold Dragons are hidden behind the nearby Rampart town.)
To beat this monster boss, one of the biggest I have ever seen:
I have orb of vulnerability and mass berserk. Use Phoenixes to lure everyone into one big heap, and Archangels to resurrect the Phoenix, because they'll get killed very fast by unberserked units.
She has magic resistance, so every turn your mass berserk won't trigger on someone. This is a big killer, because untriggered units will ignore the Phoenix and march down towards your shooters, thereby leaving the Berserk mob. After a few turns you will be stuck berserking only two stacks at most. I suspect battle would have been unwinnable if Thorgrim was the enemy.
Marlindra's forces are way too powerful to beat without Velda's archery specialty. Your melee fighters are practically babies in this battle. I hadn't thought to do Demon Farming when troops started carrying over two maps back, but probably a demon farmer would have 10000 demons by now making things easier for him.
The real winner for this battle was not my genius but AI stupidity. AI has counterstrike, fire aura, air shield, etc. They would have crushed me given enough time, since after 3 turns the troops are all over the map and berserk can work on only 2 stacks at most. But AI chose to misuse one of the most powerful game turning spells - Sacrifice. They sacrificed weaker stacks to revive their unicorns twice. This was a huge mistake.
On paper, sacrifice looks good. The AI can never pass up a chance to turn 100 level 1 units into 100 level 7s. In practice, this spell is only for human players. It's another example how sophisticated the Demoniac player has got to be. Sacrifices lowers the numbers of stacks you own or have access to via resurrection. I don't use sacrifice. It prevents me from resurrecting my units at the end of the battle, and it lowers the numbers of stacks I have on the field thereby reducing my options. Even one peasant has his use - for soaking up retaliation. AI also can never pass up the chance to kill a stack without retaliation, so I like to have weak, ineffectual stacks cluttering the battlefield and wasting AI's turns.
Having clued into this, once I have confirmed that I can blind, I encourage the computer to sacrifice, by targeting their strongest stacks. Predictably computer will sacrifice. This gives them one huge power stack - one that I can blind or berserk. So even my 103 Titans being slower than her 269 Gold Dragons, became an advantage. I walked away from the Goldies and cast Berserk on the 2000 Unicorns who helped me kill the Goldies. Then I blinded the Unicorns next turn, since Titans are faster. Marlindra was one turn away from killing me totally since I had nothing else at that stage, but the advantage of spellpower 99 blind is that from then on, I could resurrect my entire army and Marlindra was lost.

I have found this one-stack targeting strategy extremely useful. In one scenario, I had to face a vast army that included 500 Archdevils. That stack of Archdevils could kill any single stack of mine in one blow, Frenzied or not. On their own they were more powerful than all of my 7 stacks put together. But instead of blinding the Archdevils, which I could do easily, I focused on killing them which appeared harder.
This made the computer 'resurrect' their losses by sacrificing other stacks that were trapped behind castle walls.
In other words computer killed its own stacks and reduced its chances on the battlefield for me. And since I was the besieger facing tower arrows I never had to worry about blind.
When we got to 3 of my very weak stacks vs 500 Archdevils with fire aura, everything seemed doomed. But what followed next was Blind, Resurrection of Army, Clone, Prayer, and 500 Archdevils were gone. AI never had a chance once it was 7 stacks vs 1, since, they could kill only 2 stacks per turn max. To save mana, I even killed my own catapult leaving 1 tower, so that I could benefit from the free destruction of my clones after they'd resurrected every turn.
