After some preparation and research, we prepared ourselves to delve into the Doom Vault, and the extraction chambers. Though we had some debate on what we 'might' find there, we ultimately determined that speculation was driving us in circles, and we need to just go in. We encountered some resistance, but managed to free three of the prisoners, those that we believed Szass Tam was drawing power from, people not from this realm, in an attempt to ascend into godhood. I have a feeling we will meet him one day...
We continue to push forward, expecting further resistance. At some point, we expect to encounter Tarual Vaul (sp?), but it is also possible to encounter the lich that built this complex Kazic Goul (sp?). I am not sure how we can counter such powerful magic, but I hope Gnipity has something up his sleeve.
