It was time to begin the attack on the valley. The ninth knot gathered their forces near the cliffs at the entrance to the valley, about 1000 yards from the tower. Mardoc cast a spell that allowed him to communicate with some of the leaders of the army, and then he, Gardain, Chantra, Damien, Izevel, Raiju and Grumblejack advanced half-way to a spot under the wall, about 500 yards from the tower. While Grumblejack, Raiju and Chantra waited at that spot, the rest used dimensional doors to appear in the fourth level of the tower, just outside the soldiers’ barracks.
The two guards were killed quickly, and Mardoc manipulated the stone of the wall to lock all the guards inside their barracks. Damien sent a telepathic order to the duergar forces to advance and then they headed up the spiral staircase to the roof, where they knew to celestials were waiting. Two quick banishment spells got rid of the celestials before they could react. Also on the roof was a big brass gong, secured by sturdy ropes. No one at the tower would have any chance to operate it.
Mardoc ordered Grumblejack, Raiju and Chantra to advance, and they did, the oni flying through the use of magic and the ogre using his wings, each of them holding Chantra under one of her arms. They tried to sneak on the two soldiers patrolling the east side of the wall, but they noticed them, and attacked. They did not present much of a threat to the trio, though. The pair of soldiers on the western side of the wall were dispatched of similarly.
The party then headed to the third floor, where the elite forces were barracked, as well as the captain of the tower. That fight turned to be a little harder then the previous two, with the Captain doing some real damage to Grumblejack, who had to withdraw from the fight in order to get some healing. The fight involved 6 knights and the captain, with 5 more soldiers climbing the stairs from the floor below to join the fight, but they were never much of a threat to the party.
Climbing down to the second floor, the party noticed that one of the doors leading to the walls was open, and assumed correctly that one of the guards escaped to rally the forces. They were now eager to finish cleaning the tower from defenders so they could open the portcullises and let their army pass. But cleaning the rest of the tower was a doozie, with two small groups of guards and knights populating the guard rooms on the first floor. The two clay golems in the corridor through which the army would pass were also easily destroyed, as they seem unresponsive to Damien’s attacks from outside of the tower.
And so, Mardoc ordered the forces to pass through the gates and into the valley. But as the army was passing, they could already see Mitra’s forces arriving on the field of battle on the other side of the canyon.
Since the party managed to take over the tower without the alarm sounding, they gained automatic surprise. They also gained the benefit of positioning their forces on the north side of the wall instead of on its southern side. The defending army, on the other hand, could not muster all of its force on time, and some units are straggling behind, to join the battle only later.
