Onto the dark realm of the dwarves. Sindri is a great dwarven gold smith, and Brimir is the giant who's blood formed the dwarves, although here it seems to refer to the first dwarf. Sadly the dark dwarves will also side against the gods in the last war.

Voluspa - Norse Mythology Book - Verse 37

“ Northward a hall |  in Nithavellir

Of gold there rose |  for Sindri’s race;

And in Okolnir |  another stood,

Where the giant Brimir |  his beer-hall had.”

Bellows Translation
