I just jumped into a river outside of town to go after some jumping salmon in a waterfall and the river swept me away on the current. I just thought it was a pretty cool thing to have happen. Feel free to post other neat environmental observations you may have.

I like walking around scorching the rocks and ground with magic. It's pretty cool how you can see the seared earth. The northern lights were also very awesome. I'm glad I didn't look up spoilers before starting the game!

Old news, Todd showed it during the Quakecon demo
