This is on the l3e.org Minecraft server. I used the dynmap to find a snowy mountain, and in my experience, that is where the Warden is usually hanging out. After some clumsy exploring, I landed right in the middle of an ancienty city. Then, I used my Titanium sword to kill the warden with just a little health leftover. I will have to go back to that ancient city later and see what goodies are there. Check out the l3e.org server. The server IP address is also l3e.org.
