Guild Wars 1 added some new content yesterday. It opened up more of the Northlands and added a 3-level dungeon to pre-searing. The reward is getting Devona as a hero. In pre! You can also pick her up as a hero if you're already out of pre-searing.
The dungeon is stunning and makes very good use of the new tech they added for lights and shadow.
There we parts of the dungeon that made me go "holy shit. wow" and I've not added them here, as I really encourage people to go check this out. Most of the mobs in the dungeon are around level 8, and woo I did a lot of dying. I don't have a fully decked out pre-searing character, but I would maybe not recommend going in below level 10 or so, or if you do bring a friend.
The whole process of finding the dungeon, doing the quests took several hours, so take a break in between the quests or something, and the dungeon quests themselves took me 3 hours. I was really taking my time and exploring, and running back from the res shrines a lot. Bring your Fire Imp with you :D. When you get to the point where Devona can join you, do note that she will self-rez when fights end.
But yeah, if you have a pre-searing character around level 10 or higher, I highly recommend giving this a play :)
