Completely Unrelated Question Time :
I've seen it mentioned that the Daleks used to be a race called Kaleds before, which is kind of hilarious... but when I saw a Town Called Mercy and the alien doctor's race was the "Kahler" I
immediately thought of the Kaleds. First off, they sound the same, ergo, they
are the same, right?
Secondly, they're both super advanced civilizations, right? With smarty brains and technology that's centuries beyond human understanding? And they both invested a lot of energy into creating the "perfect soldier" by merging man and machine in ran effort to end a horrendous war. I've never seen the Dalek origin story but that's the way I understand it, at least. Any chance they're related, or that Kahler Jex is at least an homage to the Kaleds or something?
Have the Kahler ever been mentioned in any previous stories?
