So Bahamut's generally seen as the "good guy" god and tiamat the "bad bitch but not in the good way" right?

I have a bard character who beat tiamat in a card game once (astral drifter background) but I don't know that much about her lol

Don't worry, I am heavily adapting them for this setting, so previous knowledge of their D&D-related counterparts is not necessary XD. 

A little about the gods:

Billions of years ago, at some point after the Big Bang sparked the universe into existence, subatomic globs of primordial ectoplasm throughout the Aetherscape began condensing into larger clumps, eventually becoming something akin to giant glowing space jellyfish with partial cosmic sentience. Modern Magi refer to them as Proto-Gods, and they gradually evolved as the universe expanded and the first signs of life in the Mortal Planes began to appear. Eventually, fragments of the emotions, memories, and dreams of the Mortals began bleeding into the Aetherscape, which sparked the Proto-Gods' transition into the Celestials, the first true gods with greater cosmic sentience (sometimes they are also referred to as Elder Gods or Old Gods). Although it should be noted that no known entity in existence comprehends the full history of the universe or what happened prior to the Big Bang - that is a mystery even the gods have never solved. 

The Celestials created the first Prime Nexus Points as they crossed over into the Mortal Planes, silently observing the development of life over many millions of years and employing a strict non-interference policy. After living extremely long lives, they began to feel their energy dim, shocked at the knowledge that even they could grow old and die if enough time passed. Deciding their power could live on in the hands of lesser beings, they began writing the first Arcane Tongues and embedding them into the fabric of the Aetherscape. Selecting chosen Mortals from various races to ascend to godhood, the Celestials taught them how to use magic and then gradually faded from existence. These new deities came to be known as the Ascended Ones (sometimes called the New Gods).

In the planes connected to the Prime Nexus Point on prehistoric Earth, the Ascended Ones included Dragon Gods, Fae Gods, Beast Gods, and Storm Gods, to name a few. Though, it's important to note that none of them knew about Black Mana at that time - the Celestials had deliberately pushed that aspect of the Aetherscape deep into the Outer Void in the hopes no one would ever venture that far. It wasn't until millions of years later - around the height of the Roman Empire - that a group of Cerebromancers first discovered Black Mana. Another thing to note is that the Ascended Ones have long lifespans, but that is only a blink of an eye compared to what the Celestials had. For instance, Bahamut and Tiamat have been alive for about three thousand years and are already considered "old."
