Dwarven Lore?
Playing Guild Wars 1 would be your best bet- they were still a thriving, vital culture back in that game, and you might pick things up wondering around their areas or hanging out with Ogden.

That’s definitely true. You would be best off playing GW1 and watching WP’s lore series (should have something on the Dwarves). Not sure if Deroir has something on them, but he probably does.
