The introduction confuses me.
Arta was curious to use the time machine, and went back in time thinking she was invincible!
This quote makes her sound more like a little child than a genius.
Also does that mean she is from the future? seems to indicate so, so that means she went back in time to the start of the Rodesa war thinking she can handle anything.
That doesn't strike me as anything remotely close to a genius, unless she intends to launch a nuke at the dark elves and orcs, and go back to her future to say "war prevented, job well done"
