"The rats turned tail when they felt the presence of this portal's energy and no doubt took the wee one in the process." the dwarf explained before looking to the portal, "We can investigate but the rune pattern suggests something undying and a place for it's sactuary, even the undead need a place to rest their head and recoup Reszket. In a tome some time back I read of something like this, it suggested some of the elder gods long forgotten and unknown to the younger races entrusted their most powerful rites to those who would sacrifice themselves to their deity, reborn if their faith was true as an undying servantor to their god and religion, in this they would not falter due to earthly desires, age, disaster, or calamity. Some championed and protected an artifact, others safeguarded knowledge... the wrinkle in all this is was a daft noble would have the stones to build his home over such a place. They may have been in a deep sleep or trapped here... maybe helping they have a task we can help with and they would in turn help us... these areas seem cut and worn of stone older than the mansion by some time." he explains stroking his beard as he smoke a snare on his face... Nothing like assisting the undying in a murdering spree... it's better to side with the undead at times than be in their sights to be consumed.
