Wow, this is the first time I've made a topic and had it get to the second page in one night. Anyhow, I've looked over what everyone has said, and it does seem to take place in the present. This is, of course, assuming Tyrannia is a "lost world" type thing where prehistoric stuff was kept in isolation and as such never evolved, and as I recall, didn't Lisha and the others reach Meridell through a time warp in the ruins? That would make Meridell and Brightvale actually ruins, it's just that the time warp seems well known. So, Present time/Dark Ages, depending on where you are
Oh, and the reason I made this topic? There's a comic I'm gonna make once I learn how to draw, and this is a rather important question. Do I have the main character hear of the crisis over the tv, through the paper, or turn on and old tyme radio

. Is it logical to have an enemy besides Dr. Sloth capable of building a massive army of robots bent on destructions? These questions must be known!
