The bond you feel with the sea serpent touches also the bond you feel with Bahamut, in his aspect of God of the Sea. You find yourself thinking and dreaming of the ancient past of the dragons, when they emerged from the chaos of the sea, moving towards the order represented by the land. Frogfolk becoming sea serpents becoming the first dragons.
In your dreams you see the carving away, the infinity of chaos giving way to the single, gem-like facets of identity. Bahamut is rooted in the sea, multivalent and shining with all colors from his platinum hide, but his teachings were a
return to the Sea, an embrace of Chaos after Tiamat's overdose on order. You've never worried about these things, doctrine and alignments; your connection with Bahamut was primal. And that's how he likes it.
But now he needs you to understand. You see the first draconic spirit, a ball of infinite possibility, and how it came to know itself; how by defining itself, it broke itself into pieces, shedding identities like shed skins. You understand why Tiamat feels that all the other gods were once a part of her and could be again; all of them were a part of something greater once, and Tiamat, control freak that she is, still sees herself as that greater thing.
You see, however, that she, too, was cast away; Tiamat, Lawful Evil, and Erathis, Lawful Good, were the last masks to be cast away. (Erathis, your own progenitor as a blue dragon, and another god of storms...) And then all that was left was Primus, eternal order, perfect understanding, who departed the world forever.
And shattering that perfect order, the revelation of Bahamut. Bahamut led your people back to the sea, and taught them that only by embracing chaos and that total potential can you reach back to that ancient draconic spirit.
Tiamat thinks she can get there by eating all the gods. You understand Trionyx's heresy now, and are immune.
