Day 8! Today was Spectral Brilliance Hidden upon a Dagger, or just... Dagger :)
He's longdead, and a species that's gone extinct from the crystal trade back in the day. However, he's sort of responsible for the biggest problem in the universe- He's the "father" of the Dealer, and supplied their stock for Way Too Long.

("Father" as in being the father of the man who cloned Dealer off himself, so technically hes still Dealer's father)
