So, the nerve cord khala thing that the Protoss have? How long has that actually been a canon aspect of their race? I never played Starcraft 1, so I'm just going off information from Wings of Liberty and forward, but I thought that was just a really long ponytail. Not some kind of nerve cluster like from the Avatar movie. The reason I'm asking is I'm mostly just curious if this was established before that movie came out or not. Not really worried if they did rip off James Cameron with this idea, or vice versa, just curios, since I know the original Starcraft game was around long before that movie, but I don't know if the nerve cord/khala thing was you know...a thing that far back.
