You send out messengers to all the nearby lords and kings, to gather their men. The orcs cheer when you tell them that the invasion is coming, and Silanius returns from a quick teleportation trip, bringing the Orc warlord Krush, who eagerly promises that his army will make best possible speed to the fight.
Silanius predicts that the gates will open throughout the temple complex, and so you plan a circle of fortifications surrounding the complex, meant to contain what is within. With your incredible strength, and the magic of the wizard and elves, the walls rise and enchantments woven into the stone, that hell itself may not breech them as long as the walls were held.
And so you labor as warriors, knights and soldiers trickle in. All are impressed by your presence, and heartened by your labors beside them. Some are afraid or enraged by the orcs, but to see their ferocity turned to the enemy of all that lives heartens them enough to tolerate their presence.
The council works out a rotation of warriors and elves to fight as long as needed until the orc army arrives. The orcs do not need rest, so they are able to fight without rotation, stopping only to eat (for demonic flesh is not good). You as well prepare yourself for a long battle, as you have yourself lost the need for rest (though you do find it pleasant still).
Finally, the day of the invasion arrives. There is a dark pressure in the air. You stand atop the battlements as storm clouds unnaturally form. Your armor was reshaped by the finest elf smiths, to be strong yet not restrict your movements. They also weave spells that will allow you to communicate with your allies, and allow them to track your location.
Princess Celyria joins you, armored in plate and bearing a longsword on her hip and a bow in her hand. All the elves were armored thus, excepting some dedicated casters spread through the walls. The wizard watched in a tower he summoned set back overlooking the battle, he would be providing support where needed.
The Princess nods at you, and you jerk your head at her. She smiles briefly before turning her attention to the gathering storm.
You talk a bit. You learn she is the youngest and last princess of the elves. She had proven to be extraordinary skilled even among elves, and has pushed hard for the kingdoms to end their isolation and try to use their powers for good. The demons attacked, and she proved vital to pushing them back. She took a small force with her to try to unite the world against this threat. She heard of you, and fate would have it that she would encounter you here.
You mention your mother and losing her, and the stories of your first battle when the horns resound. You feel the ground tremble as a dozen and one gate/ emerge from the ground in the temple complex, each towering over the temple buildings and reaching nearly to the height of the walls, formed of dark stones inscribed with demonic runes. Legions of demons begin to march out, only to scream in pain and collapse as they walk into extremely purified holy water that was flooded into the enclosed temple complex. Thousands of demons stumble and collapse into the water before flames of darkness emerge from the gates and burn away the water into a heavy steam.
Thousands more of the demons pour from the gates, and as they leave the temple grounds arrows begin to fly from the elvish archers, who are unnaturally quick and accurate. The Princess herself claims two demon lords in as many breathes, her arrows piercing eyes and heads. She quickly fires the rest of her quiver, and reloads from the “autoloaders” that they had installed all over the walls.
At the moment they still use the temple buildings as cover, they cross the short distance to the walls. Once they reach a few feet, they are slowed immensely, allowing even human archers to get a good shot it. Touching the wall sends a powerful into their bodies, often blowing them apart. The temple buildings swell, and demons march to the roofs and try to leap from them to the walls.
At the moment that it seems that the demons would start to crawl over each other, the temple buildings explode, sending magical fire roaring over the many thousands of assembled demons, and a shockwave that causes the gates themselves to tremble. As the smoke clears all that is left is scorched earth, and 13 gates shining red.
All is still for a moment, before a demonic horn blows and giant demons charge out of the gate, howling into the sky, and more legions march at their feet.
Your time has come. What do you say, and what do you do?
