Things learned so far

First, I'll refer you back to this post, which summarizes some things already learned about the Bahumati and documented in the diary of Gaius.

In this last session, Surina told the party that in her land "where the winters are cold" the Daruns and the kobolds had gathered together villagers from many dragonborn settlements. They asked them to move to a large town that they had built among ancient ruins. The ruins could be fairly frightening. Sometimes the walking dead or other nasty creatures emerge from the tunnels underground. But the kobolds are determined to rebuild a civilization there. And they are obsessed with exploring the underground, in search of artifacts from the ancient past. Specifically, they believe that Merdosh can help them find a powerful item know as "The Crown of Trakas". (and a high roll on a history check by Junter revealed that in ancient days, a warlord known as Trakas Wingsong was a conquering leader in the north).

Merdosh tells Perra that the kobold and Darun had told him that he was going to grow up to be a great warrior.

When Nadarr hears all of this, he connects it to something he'd seen in the capturing orb. It's an ancient painting of a warrior king. This king is a dragonborn with black scales and red markings, just like Merdosh. He stands on a step pyramid, next to a green dragon, and a horde of soldiers bow before them. This king's name is Trakas Wingsong.

Nadarr also reminds the party of this knowledge: The contents of the capturing orb can be divided into 4 categories.
1) Tales of the “First Age” are the ancient mythology of the Bahumati. They are the same stories that any patron of Bahamut would have learned, but with a particular spin. While Bahamut’s followers view him as noble, just, and honorable, these tales present him as timid, indecisive and weak. Tiamat is always presented as the wiser, bolder, and more effective figure. Bahamut turns the other cheek, while Tiamat stands up for herself and her draconic children.

2) A history of the “Second Age”. This presents the time period that preceded the plague 1000 years ago. It details the rise and fall of kingdoms in the ancient terre malatia. Dragonborn wars among themselves and against the demi-human races are described.

3) A prophecy of a “Third Age”, where Dragonborn and Demi-human alike would fall victims to a deadly disease. Anarchy would reign for a millennium.

4) A prophecy of a “Fourth Age”, when the Dragonborn kingdoms would rise from the ashes of the Third Age, and defeat the demi-human scourge once and for all.
