Well, I've been fighting the many monsters running around in Esthar City. I have no idea where I'm going at this point (it's been so long), so I just randomly did some exploring. Anyway, I saw the weird guy standing and talked to him, which lead to the bizarre "Heehahaheehee", and eventual battle with Elnoyle. In another part of the city, there was a guy doing a similar laugh, who the people nearby were considering traumatized because of the Lunar Cry going on.
Now, I was wondering: is the weird guy encountered before the battle actually an Elnoyle laughing at you? Or was it likely a human that eventually transformed into an Elnoyle? The latter seemed to come across my mind when considering the other guy that was laughing hysterically.
While the Elnoyle seems like nothing more than a mindless monster in battle, the laughing before the battle seems to indicate it has some sort of understanding. I know the many monsters were attacking the people in Esthar, but I believe it's implied the monsters from the moon were also turning people into monsters as well. Either that, or the monsters are more intelligent than I thought.
Just had this on my mind while playing through. I know this is totally random. Hopefully it's not too much.
