Not really the official ref (meaning there will be another to come), but it'll have to do for now.

Col and Lector are a build up of two Assets; a Lethal Parasite (Lector) and it's Host (Col). Meaning they can deny the other's actions to a certain degree.

And originally some Bio would go here, but I'm currently piecing it together, delicately and slowly. So it doesn't end up being the well known "Horrible past" backstory or something of the sort.

Yet I can tell that their personality isn't a one sided dominate over the other.

So here you go Col and Lector or Collector
