Not sure if this is where to post this question, but I figured the RPers would know. Does anyone here know the full origin stories for the majority of the Phalanx or Vindicators? Like Sister Psyche, Positron (especially, I would really like to know about this one.), Malaise (sp?), or Infernal? Any of them would be great. It would help with backstories. And if this thread exists can you point me in the right direction? I don't really think diggin will get me anywhere.
