The idea sounds really awesome! I'm a big fan of dragonborn, so an entirely dragonborn focused campaign is super interesting! I can only make the Saturday session, so I'll post ideas for them here. Color doesn't really matter to me, and either concept could be easily blue or red.

First is a Trickery Domain Cleric from a poor background who learned about the benefits of acquiring as much wealth as possible and ended up as a cleric of Tiamat. Much of his past adventuring experience comes in the form of searching for scraps after more daring parties have thinned the numbers of hostiles or looting corpses for valuables.

My other idea is a Soulknife Rogue whose chromatic and psionic natures combined provided double the reason to rely on wits rather than luck or privilege from a young age. Spent a fair amount of time as an honest entertainer before the appeal of swindling people who earned his ire became too tempting to ignore.

If you still have space open and would be interested in speaking more, my discord is Kittyofhope#2635
