Simon Says

I called it "Simon Says", since I'm Simon. And with just a specfic hand movement from someone with magic energy, they could force anyone to obey a command, if you could express it in one word.

Now, I knew that wasn't true, I knew that it was that your average Human or Elf or Whatever could only concentrate on one word's worth of actions to implant.

But then a Goblin learnt it. And they consider their entire lives to be one giant word. And they're used to thinking of multiple actions in one thought.

My spell conquered the world, though.
