There's a high-level run called "Drok's Run". Its a player-name for a "jaunt" through three or four zones filled with level 24+ creatures (for those who don't know, the max player level in GW is 20). These zones connect a lower level town with the largest high-level town outside of Ascalon (the main city at the beginning).
The run through these zones is definitely entertaining. What more can you ask for... super high-level monsters that you haven't seen before, death and mayhem repeatedly, and at the end a waypoint to a great city filled with lots of good armor and skills. Death and mayhem is the part that draws everyone, right? Well, doing Drok's Run you get to see a lot of monsters that you won't encounter again for quite a few levels and you get to watch a bunch of high-level players run for their lives. Hahah!
Basically, it works like this... A few high level players get together and drag a bunch of low level players along. The lowbies die early (one attempt I died within sight of the starting gate), but they are there to draw fire away from the guides.
The guides goal is to run, run, run... oh and then run some more. Don't stop until you see the light at the end of the... uh, well, until they see the portal to the next zone. It took us at least ten or fifteen tries to get through and a couple hours of gameplay.
One good feature is that while you are dead, if you click on other members of your group you can watch the game from their perspective. So at least you can see what they are doing and how the progress is going.
Once through the Run, you reach the Dwarven city of Droknar which has high-level armor, lots of trainers, and tons of players selling stuff. And since you can easily jump from town to town using your map, you can come back and visit any time you want without having to go through Drok's Run again. Though the area certainly looks entertaining once you reach 20!
