Kyuss' ancient temple

We had to wait a while to see Tenser, but we were able to procure some valuable equipment while we waited for Tenser to return. It seems that he is aware of the recent happenings, but has been too involved in other matters to make a personal investigation. He did send someone to make some inquiries, but they have not returned so he has asked us to check up on a few things.
First off he wants us to check this ancient ziggaraut that has connections to Kyuss long ago. Tenser also gives us gifts to help on our quest.
Using an ancient mural as a focusing point we teleport directly to the temple.
The pyramid is encircled by a massive black stone wall. Flying over it we see that the ground is crawling with the green worms. The wall seems to have been constructed to contain whatever exists inside this structure.
As we cross the wall we are greeted with visions of times long past. We see what must be Kyuss at the height of his reign.
We pick a black opening in the base of the pyramid and begin our exploration.
Clacking and chittering seems to be emenating from within. It grows louder as we near a chamber. Several large beetles are clacking mandibles at a terrific pace and an unholy undead being leads them to attack. The undead soldier has no eyes, but rather has long toothed worms in his sockets which lash out at anyone near. The clacking sound is overwhelming causing many of us to clutch our heads trying to focus on the battle at hand. The beetles are faster than one would suspect and the snapping mandibles are tearing chunks out of anything that they can reach. Desperately we fight them off and slay the undead creature leading them. Badly wounded we head back over the black wall to rest and plan for further investigation.

As we proceed into the ruin there is an enormous room with an enormous pit churned from the ground in the center. doors lie in the four cardinal directions and stair lead up to a higher level. We decide to investigate the doors before ascending.
We encounter some celestial beings, sword archons and an eldarin that have been corrupted by the power fo Kyuss. They radiate corruption and evil and attempt to lure us to our death. They unleash globs of slimy worms as they pound on the walls and ceiling. The worms tearing into any opening in my armor the toxins they secreet wearing my mind down. The eladrin launches powerful spells upon us as we battle, one of them taking a huge toll as Solara is completely destroyed with nothing remaining. We made the fallen angel pay for that, but it is not enough.
We returned to update Tenser on our discoveries that the temple is active and powerful creatures lie guarding it within. A associate of Tenser from another plane, a githzerai has offered to help, and we accept needing all the help we can get.

Back once more we investigate the other doors, but they don't lead anywhere. More visions appear to us as we investigate giving us a chilling account of the attrociaties that Kyuss performed here.

We decide that the chasm is our next avenue of exploration. As we decend we see that tunnels are burrowed into the sides of the shaft. All of a sudden we are assaulted by large worms with the head of a man. They radiate a powerful aura that snaps mortal minds leaving them dimwitted. They also unleash powerful spells upon us. If is all we can do to retain our minds as we fight these horrid worm naga off. All but Nallec and I have had our minds crushed by these things. I barely retained my mind almost giving in to the insanity that radiated from them.

As I spend the next day restoring the shatter minds of our team I wonder what horrid monstrosities are to be found in this cursed place. Wee Jas give me the strength I need.
