Quests

 * The Third Seal

 * The Avatar of Darkness must survive
 * Domina must survive
 * Kill the Renegade Mages
 * Guide the Avatar of Darkness into the Portal

Hints
This mission is - for a last mission - quite simple. You can build Beholders for the first and only time. Produce an army of them and mow down your enemies.

When these are gone, you can open the Third Seal with Domina and two Matriarchs. You should gather your army there because Ruannon's order is mobilizing it's last reserves to stop the Fallen. Renegade Mages spawn constantly that are much stronger than the standard mage and will try to disturb the Matriarchs at their ritual. In this battle, several Beholders will die.

The breaking of the Seal takes 5 minutes.

It is not necessary to destroy the Empire and Beast bases since they are actually fighting each other. It is recommended, though.
