One time a couple of years ago I was outside the map below deadwood and I somehow came upon a shop of some sort. The shop owner looked like Azreal from Azreals night club and he would talk to you(can't remember what he said though). There was a few breakable health pots but that was about it. After doing a little more wandering I came across a half working spar arena. There were warps that could take you spectator seats and to the battle area. When you would sit in the spectator seats the camera wouldn't show the whole arena so it obviously was never meant for idevice use.
Sadly, I got stuck in the spectator area and had to reconnect. It is probably my favorite Graal memory because I'm probably the only one, or one of the few, who ever got to go there.
