No, eriana 3 was the last of the praxic fire. A warlock order, who were a... Bit more irrational in lack of other words,. She was a close comrade to eris, and was the lone survivor ( scratch that she and eris are) who survived the great devastation: the battle in which the shadow of crota pillaged and massacred thousands of guardians to claim the moon. On that day she vowed to claim her vendetta. She would get revenge even on her las life. I would go into more specifics. Though I wouldn't like to tell of the gruesome occurrences of eris' fireteam And pujari was a thauntonaut. Thauntonauts are warlocks exclusively. As we are the only class who have intentionally killed ourselves for revelation in knowledge. By doing this, pujarai had a dream of the black guardian. Which is how we came to discover its existence [spoiler]WHAT?!?! IT'S NOT CRAZY!!!! WE'RE NOT CRAZY!!!! YOU'RE ALL THE CRAZY ONES!!!! ESPECIALLY YOU NAPPA[/spoiler] but yeah they are warlocks
