While I do understand that the DM is ostensibly God in his game. My GM does generally respect most things written in book.
I have a character who is connected with the Shadow Plane in a E6 D&D3.5 Pathfinder Hybrid game, and I was talking to my DM who said that nothing lives in the shadow plane. However, I am sure that that I've read about some creatures that are native to the Shadow Plane. In addition, I think there's a template to turn creatures into Shadow creatures.
What published examples can I show him within our scope that prove the Shadow Plane has significantly inhabited regions?
I'd appreciate answers including page numbers for any referenced materials.
D&D 3.5 (No 3rd Party) + Pathfinder + E6
I would like to know of anything that is outside the scope of E6 however please note it as such because it will need extra special DM approval to use, as well as a good explanation as to why I should be allowed to use it.
