Hello,
After being impressed with Mitlanyal, I was curious if there was any information published on the dread Pariah Deities. Any information is much appreciated. Thanks!

I am in no way an expert but there are some bits and pieces scattered across several works. Now I haven't read it myself, except for the free preview, but I understand that the PDF "The Tongue of Those Who Journey Beyond" has some interesting stuff in it.

Otherwise what I think I know is in general the following.

1. There are three Pariah Deities; the Goddes of Pale Bones, the One Other and the One Who Is and each of them seem to have a goal for the universe that is less than productive; eating it, reducing it to singularity or its total enslavement

2. Their worship seems to be as old or potentially older than even the Tlokiriqáluyal/Lords of Change. The goddess of the Pale Bones was for instance well established when the First Imperium was created.

3. The Goddess and the One Other was relatively popular at times in present day Five Empires but have since been purged in an act of persecution never seen before or after. Some remains of the cults are thought to linger and outside the Five Empires its very possible that there are people who worshipp the Pariah Gods.

Gurkhal has hit on the main source. There is nothing comprehensive about the other gods of Tekumel. Perhaps someday we will get another volume or 2 of Mitlanyal. The Goddess of the Pale Bone is a relevant to events in the novel Man of Gold, and also Prince of Skulls -- they provide some additional perspective. Priests of the One Other make a brief appearance during an Imperial funeral in Adventures on Tekumel 2:1 (the light blue book). There's really not a lot to go on.
