CAST technology's jus' like anything else, always changin' an' improvin'. Now there's a lot I don't know about Gurhalian history, but I do know what I am now ain't what CASTs used to be when they were first made centuries ago. Back then th' human designers were lookin' to create adaptable machines that could replace humans in hazardous workin' environments, such as th' hard vacuum of space.

My original homeworld had a different approach to android technology, I'll admit. Took a lil' gettin' used to when I got an overhaul.
