Hey Greg. I just had an idea. We don’t know where Nidhiki’s from, but it’s somewhere that Toa either attack from the shadows, or they don’t live to attack at all. To me, that sounds awfully like the Tren Krom Peninsula. So, my question is, was Nidhiki from the Tren Krom Peninsula?
Yes, he was
So, was Nidhiki originated from the peninsula or not?
