Fairy Quartz's Links
Fairy Quartz was the one that made Bloodstone shatter Spinel as punishment; and to keep the great weapon under her thumb.
Fairy Quartz is Bloodstone's boss.
The only reason Bloodstone follows her is because Fairy Quartz blackmails her with the fact that she was in a forbidden relationship with an Spinel. She despises Fairy Quartz for making her shatter her love.
