Discovery, Exploration
You have gained access to the Temples of Extraction. Supposedly, somewhere in this sector is a way into the Phylactery Vault so that you can end Szass Tam and every Lich in Thay for good!
As you continue to explore the Temples of Extraction, you continue to find raised daises with humanoids trapped between four pillars. While Brehana Warpip was able to deduce how to disrupt them and free their respective captives you have chosen to wait until you have more information on what might happen if you were to do so.
Among the Red Wizards and undead you keep facing off against, though, there is one that seems different. His vision is glossed over and his voice pattern quite monotone.
Using detect thoughts on him, Brehana Warpip is able to determine that he is actually a member of the resistance that captured the Gatehouse. His name is actually Mennek Ariz and he was captured and brainwashed by the Thayans. Using dispel magic, Malice Bloodmoon is able to restore his mind and though he is a bit confused, Mennek is able to convey what little he was able to find out about what he calls the Shrines of the Chosen.
Each of the Shrines is powered by a Chosen One of a deity. Szass Tam believes this power will help him in his quest to become a god. Tennek knows they along with the black gates are some how tied to the Phylactery Vault but he is not sure how.
After escorting Tennek back through the black gate so he can return to the Gatehouse, you continue onward finding yet another room with another shrine. After subduing the Red Wizard here you quickly dispatch the undead, gray oozes, and ochre jellies. You then tie up the Red Wizard here hoping maybe she will answer some questions about these Shrines.
