After questioning Santron and cooperative, yet fearful, court scholars knowledgeable about Bahal'din'Murr, you are able to ascertain that general teachings of their religion are heretical, yet not directly related to the Ruinous Powers.
However, there are many references to hidden theology, essentially a higher set of hidden beliefs that have on tangential relationship to what is taught in the temples to the common people.
Furthermore, it appears that the priests of Bahal'din'Murr are at least somewhat familiar with sorcery of some sort - your agents find many smashed intricate devices that might have been used for communication, divination or some other purpose. Some priests, under torture, speak of Cosmic Harmonies and how Bahaldin opens them for humans to use.
Canoness Engel expresses her opinion that in worst case, the twin faced man (the most common depiction of Bahal'din) might be a strange avatar of the Chaos God Tzeentch.
However, the link is not yet confirmed for sure.
