I was just playing some missions and thinking about this the races in Destiny all seem to have a basic characteristic of one of the seven deadly sins
Lust- Taken (male /female...light/dark)
Gluttony-Calis/Cabal
Greed-Hive
Sloth-Vex
Waith-Scorned
Envy-Fallen
Pride- The Gaurdians
This is just an observation and I can go into details why these fit so well but I figure if I am posting this on the Lore section most of you will understand already. Just want to see what others think of this.
