I've updated my [url=https://www.roleplayerguild.com/posts/4415199]character sheet[/url]. I think it's pretty much ready, although I would appreciate anybody's feedback.

My character sheet got a little into dwarven culture, so for anyone who cares, this is what I've come up with so far:

-Dwarves live mostly underground in the Undercomplex.
-Dwarves like shiny things
-Dwarves mine for shiny things
-Dwarves like making things out of metal
-Dwarves have "lineages" of families specialized in one industry or another, and also have "unlineaged" people that didn't particularly like their family's specialty
-These lineages are often literally named (eg "Reedsinger" for musicians) ((ironically, modern Reedsingers make brass instruments....))
-Dwarves have feasts for various precious-metal "Hearts of the Mountain". These feasts include food, crafts fairs, and tribute of the appropriate metal
-Dwarves have cities in the Undercomplex

This in addition to [@AngelofOctober]'s "Dwarves are Loners" and [@Whiskey Business]'s "Dwarves and Elves get along much more better than Humans". Those statements would imply:

-Dwarves are annoyed at humans trying to literally lord over the land
-Dwarves think working at forges and mining for shiny things and expanding their industry is far more important than "diplomacy" or "trade"
(-This isn't to say the Dwarves don't engage in diplomacy and trade, just that diplomacy and trade are done in service to engineering and industry)
-Thus, the only reason the Dwarves are closer to the Elves is that the humans started to get in the way of proper Dwarven business while the elves have kept their high-falutin' noses out of it
