The Draconic Pantheon

First of all, if you are the type of player/master who is only interested in the lore as it is in the books and separates it by editions, this post is not for you.

If you are one of those who criticizes any edition except the one you like, this post is not for you either.

With the release of 5.5 I have gotten the urge to plan a campaign again. I have been wanting to do a massive dragon-themed campaign for a while now, in my group of friends we like to play levels 3-20, so length would not be a problem for that, I have the idea that the story of said campaign is the return of the dragon gods from past editions, these are the ideas I start from.

1. The Thanes of Sardior are looking for some artifacts to restore Sardior, but they also have to deal with the Obsidian Thane.

2. Tiamat gathers her army, including the god of kobolds and the 3 demigods in her service (the demigod of urds was reluctantly accepted back by order of Tiamat).

3. Bahamut alerts the Triad and other gods of the lawful good of the strange movements of Tiamat's followers.

4. The diviners begin to have visions of clashes between dragons and people begin to fear a repeat of what the Cult of the Dragon tried in the past but on a larger scale.

5. The two halves of Argorath's incorrupt body are found.

6. Multiple gods begin to mobilize their cults, such as Vecna ​​or the Three Dead.

7. The gods that I will take into account are the following:

- Asgorath: Greater deity and head of the pantheon, his initial state is being split in half by his death in the War of the Dawn.

- Zorquan: Greater deity of the true dragons, he is the only one I don't know where to put him, but I am clear that he would not have his divinity and would be a Greatwyrm without a specific type, as well as the most powerful of the ancient gods.

- Bahamut: his status is canon, but now being a Greater deity.

- Tiamat: same situation as with Bahamut.

- Sardior: Greater deity of the gem dragons and secrets, he died with the first world and the Thanes have been trying to restore him since then, they are close to achieving it.

- Kereska: Lesser deity of magic and creativity, her appearance is that of a prismatic dragon, I consider that this deity collapsed in the Spell Plague, perhaps the remains of her power are in the hands of Mystra.

- Faluzure: Lesser deity of necromancy and dracoliches, lost his divinity and is now an exceptionally powerful shadow Greatwyrm that inhabits the Shadowfeel, I want to connect him to Vecna.

- Chronepsis: Lesser deity of death and destiny, lost his divinity and is now hiding in the Outlands, his appearance is that of a black Greatwyrm, I want to connect him to the Raven Queen.

- Astilabor: Lesser deity of wealth and status, lost his divinity and is now a topaz Greatwyrm in the Astral Plane.

- Task: Lesser deity of greed, lost his divinity and was forced to submit to Tiamat, who keeps him alive for fun, his appearance is that of an exceptionally powerful Greatwyrm covered in gold and jewels.

- Garyx: Lesser deity of destruction, his status is similar to Task's, he is now an exceptionally powerful red Greatwyrm. - Tamara: Minor goddess of life and mercy, survived the Spellplague but lost her divinity and is now an extraordinarily powerful silver Greatwyrm serving Bahamut.

- Lendys: Lesser deity of justice, her status is similar to Tamara's.

- Aasterinian: Demigoddess of creativity, her status is similar to Tamara and Lendys, but she is a bronze Greatwyrm.

- Hlal: Demigoddess of humor, survived but lost her divinity, is now an extraordinarily powerful mercury Greatwyrm inhabiting the Feywild, possibly linked to the Seelie Court.

This is the basic idea, but I don't really know how to carry it out, I was hoping to find some advice.
