What is the nature of the Runners? Are they physically different from other people?

So, the Runners are [i]technically[/i] human, what sets them apart is the Soul Gears that mysteriously surfaced when the Teras did. My main plan for this is that all the Runners were previously a Teras before coming into contact with a Soul Gear, which forced a reverse transformation back to a human-ish form. All Runners have some sort of odd feature that they had as a Teras, that wasn't fully cleansed but isint really a problem, so they have a weird quirk or whatever that no normal human has. For example, a Runner might have an animal tail, or maybe a portion of their skin is replaced by scales or an amorphous substance, whatever the player can come up with that isint blatantly interfering with the Runner's performance or sanity could be implemented. At least, as long as it's not interfering to the point where it's pointless to play that character.
