While exploring the Ascalon City Ruins in Plains of Ashford, I found the point of interest "Foefire's Heart" and behind a fence, you can see a big cave. I don't think there was any way to get over the fence before HoT introduce gliders, but now it's possible. I explored the cave system and at the end, there is a room with a fireplace with a full blue flame fire going on complete with crackling sounds. This probably doesn't bear any sort of significance, but I found it interesting that Anet would go through the trouble of adding a fireplace, decor, and such here if it wasn't possible to get there before HoT anyway. Just curious, any thoughts?
