Way to unlock: Rebuild the bridge in the northern area.
Quest giver: - (M18,20)
In this quest, you have to get to the imprisoned squad of soldiers. First thing you need to do is rebuilding the bridge by using the Power Points in the War Room. After that, you need to set on fire two pits filled with corpses in front of the stronghold (M18,20a,20b). They will be protected from your access with a magic barrier and each one of them will be protected by one Arcane Horror which may summon new undead to the battle.
After completing this quest, go to the gate (M18,20c) where you will be attacked by a strong demon who, once defeated, will drop a legendary weapon. Once you enter the stronghold, you will need to clear your way through the corpses. Moreover, you have to avoid the defense mechanism - the moving strip of light that sets on fire everything it touches.
Once you get to the very peak, you need to use the ladder on the square. There, you will find a massive mechanism which you need to spin (M18,20d). It will turn off the defense system and open the door leading to the inside of the stronghold's room.
Behind the grating, you will find the warriors you are looking for (M18,20e).
