Later, Kaspar tells the story of the sewer cult:
We were still poised at the top of the sacrificial cavern. Bailey had left us without any other options. The way down was rigged with alarm bells. So I took up a grapple and rope, hooked it to rocky crevice and walked my way down the cliff. What I saw down there was the same as Bailey had described, but I couldn't help but notice the great obelisk in the center of the room and Kegga directly in its way.
On the far side of the room the cult leader was there; and more than anything I saw the shadow of a great hulk. The same misguided warforged was standing next to Grallika.
Climbing back up, Castille was ready. Recently strengthened, he cast invisibility on us both and we ventured back down. The cavern was filled with activity. Halflings had been enslaved and were busy removing the rock that once buried the obelisk. Before we could make our way to them, however, I would have to slay the first of many whip-masters: men driving the halflings to the brink of collapse.
Unseen, Castille lifted the nearest torch from its pedestal and hurled it into the murky water the lie 40 feet below. I then thrust all of my weight into the only guard immediately before us. He followed the torch into a watery abyss. Thankfully he was still alive enough to scream. But of course, because he couldn't see us, he could only assume that his footing was weak. Nevertheless, a great commotion rose up in the cavern. Goblin archers and whip-masters began to make there way towards the entrance where Castille and I were still standing.
Moving quickly, we headed across the near bridge towards the obelisk. As a halfling was coming forward to inspect the scene, I took him by the mouth to stifle his unknowing panic. He wouldn't listen to my pleas, but I managed to tempt his loyalty by picking the lock on his manacles. With a gold piece in his pocket I told him to run. And when he hit the ladder, the sounds of bells were cause for great alarm. Where our enemies were simply curious, they now had orders from Grallika to track down the halfling.
Our footing was now firmly planted next to the obelisk. Goblin archers continually scanned to the limits of their vision looking for us, but Castille's magic was stronger. Even so, it was time for me to unveil myself. I did so with my sword. A nearby whip-master found himself bleeding at the hands my bastard sword. Before he had time to realize his situation, his body was already bobbing in the muck below.
And then it was an outright fight.
The halflings scrambled with panic. Goblin archers took up their bows and sunk arrows into mine and Castille's bodies. Grallika, too, was furious. He ordered all of his minions against us, and cut the ropes to the bridge nearest him -- effectively funneling us to him. As Grallika's troops approached, I cut the ropes of another bridge and discovered an enemy worth his pay. The lone whip-master managed to hold on. What's more, he actually climbed back to the rocky pedestal where he began. Armed with only a dagger, and a keen sense of loyalty to the Dragon Cult, he futilely threw the dagger towards us.
Meanwhile, Castille cast magic missile after missile. Grallika's mercenary archers fell. Still, the lone whip-master took up a bow and continued to fight. He was truly a man possessed by fear and the cunning tongue of Grallika.
Grallika now knew that Castille and I were not easily defeated; and so he whispered orders to his recently resurrected warforged slave. As we would come to call him, Loner, charged across the string of bridges back to the entrance where the ladder still rung with escaping halflings. But sight was a problem. While I could see even without light and Castille had at least a hint of vision, Loner was struggling. Castille had already used his Mage Hand to dislodge many torches. Only his sunrod and those nearest Grallika remained.
Castille, smarter than I, took Loner's pause as an opportunity. He called out to Loner, "You have been deceived! You fight not for Thrane, but for the evil you know as the Dragon Cult. Loose yourself from Grallika's spell. Become a warrior against him!"
Loner halted; he knew enough to question Grallika's motives. While Castille's words didn't ring as those of truth to Loner, it was enough to move the winds of change in his mind.
Grallika knew this as well. While he was struggling to order his troops, he had also managed to activate the obelisk. An evil wizard above all else, he beat Kegga into unconsciousness and tried to lift his body into the dark light emanating from the great stone. But the halflings did not have time to finish their work and the obelisk's light was too high. Grallika could not complete his ritual; could not wake the beastly demon sleeping in the water below.
Spying the danger Kegga was in, I felt a surge of speed come over me. I ran across the first bridge back towards Loner. Although he had decided to help the halflings after Castille gave him the aid of light by his sunrod, Loner was not yet my ally. I saw Castille cast another spell, Sleep, and two more minions fell to the water below. I wondered if I wouldn't be the next to fall.
Facing my one-time enemy, we exchanged only a glance. Silently but quickly I took to the far bridge, unwilling to risk words with the warforged. Across the first bridge with one left to travel, I could see the wrinkles on Grallika's face. He looked deranged. His sweat-soaked clothing was betraying the slick styling that had at first kept him presentable. He had a half-empty pouch of scrolls at his side, and already a spell on his lips.
With a severely pointed finger, Grallika uttered a single word, "jump," and I did. I know now that it was his evil tongue that drove me over the ropes and into the muck. Still I couldn't help but fear him. My muscles would only allow me to flee. I was fighting myself, tense and consumed with the taint of madness. Only the shock of that cold dirty water brought me into myself again.
I could hardly swim, but paddled over to the rocky ledge Grallika was still standing atop. So I began to climb. Grallika was busying himself with Kegga, but he caught sight of me when the noise of the cliff betrayed my stealth. He tried to knock me from my handholds and send me back to the water -- back to the unearthly beast's lair -- but I held strong. When I finally crested that damned cliff, Grallika was there. His dagger was slow, but my fist was not. I punched Grallika square in the face.
He did not fall, but I had surely announced my presence. All I had left was to draw my sword and run Grallika through. The shifter, however, had other plans. His face, already affected by the change, was morphing into that of his other self. His hide became visible hardened. "If it's the blood of a shifter I need, then I'll spare my own. Kill everyone in this cave; but the demon will destroy your world!"
Then Grallika leapt from his perch, across the fallen bridge, and over to the obelisk. His dexterity was amazing, but the fear I felt overcame curiosity. I began to run back to the obelisk. Loner, too, knew now that he had been deceived. While he was running to my rescue, I sent him back across. Time was against us all as Grallika cut his wrists. The wizard thrust his blood into the glowing light of his stony shrine.
Ultimately it was his drive that killed him. Grallika did not have the wisdom to know when he was defeated. Castille approached the wizard under the cloak of a fresh invisibility spell. Unseen and unheard, he charged his hands with electricity and grasped hold of Grallika's body. He was not dead, but upon my arrival, I knew that the villager's of Lathleer would serve justice.
