Hello! I was perusing the Grimoire and found something quite interesting. According to the Grimoire, each alien race has a sub-type of their species. The more you know :) Here's a list of them and where we could possibly encounter them. [b][u]Vex:[/u][/b] Hezen Corrective - Venus, Ishtar sink Hezen Protective - Venus, VoG, Endless Steps Virgo Prohibition - Mars Sol Divisive - Black Garden Precursors - Vex in the past Descendants - Vex in the future http://www.bungie.net/en/Grimoire/2/4611686018430701427/Enemies/Vex [b][u]Fallen[/u][/b] (they have houses instead of subtypes): House of Devils - Cosmodrome House of Exile - Card mentions them living amongst the Hive so probably moon? House of Winter - Venus , Ishtar Sink House of Kings - No mention of a specific location but have seen them in the DLC missions (forgot which one lol) http://www.bungie.net/en/Grimoire/2/4611686018430701427/Enemies/Fallen [b][u]Hive:[/u][/b] The Hidden Swarm - Everywhere lol Blood of Oryx - No specific location mentioned Spawn of Crota - Crota's End Raid http://www.bungie.net/en/Grimoire/2/4611686018430701427/Enemies/Hive [b][u]Cabal:[/u][/b] Sand Eaters - Everywhere lol Dust Giants - Usually fighting the Vex Siege Dancers - Dust Palace strike *sahilthekid* Blind Legion - "Deployed to defend vital artifacts seized from the Vex" Probably that one mission where you have to charge the eye of the Gate Lord and kill Valus's little brother . http://www.bungie.net/en/Grimoire/2/4611686018430701427/Enemies/Cabal Who knew the poor dudes we kill all the time are actually diverse/ coming from different aspects of their respective societies. Hopefully this fascinates you as much as it fascinated me , quite a lovely surprise. I'll be sure to pay attention to who I destroy next time I log on :D Feel free to discuss this and share whatever info you have :) Theories are welcome as well :D Now if only Bungie incorporated this lore into the game more effectively........
