There's a new quest-release on RuneScape: Blood Runs Deep. This quest continues the Fremennik storyline and will take you around most areas of the Fremennik Province. It starts out with a stranger washed up on the shore of Lunar Isle; and it's up to you to figure out who this person is. Eventually the storyline gets more complex and leads you to battle a new type of dagannoths.
The quest is rated 'master' so the requirements are kind of high for most players: 75 attack and strength, 65 slayer and full completion of the Fremennik achievement diary.
Of course you get something in return for helping out; 3 times 150k xp in a combat skill of choice (unfortunately, excluding summoning) and a new axe called 'Balmung'.
Blood Runs Deep seems to be a fun quest to do. The reward is nice as well; the Balmung is quite strong and grants a damage bonus against dagannoths, the new dagannoths might be useful for slayer tasks and the free xp is always nice. So I'd say it's definately worth doing if you meet the requirements. Happy questing!
With this Wintersday, Anet has introduced a new feature to Guild Wars, namely costumes of Grenth and Dwayne. These costumes are just like fashion in Perfect World and are worn over your normal armor. They have no armor value or anything, just to look a bit different. These costumes can be worn at all times and you won't have to put them away in your bags when you don't want to show it anymore thanks to 2 new slots in your equipment window. One 
for hats, and one for the rest of the body. The one for your head also serves for your season, festival hats which no longer have to be worn as an armor. Like armor these costumes can be dyed in any color you like. Grenth and Dwayna costumes are available for purchase from the In-Game Store and the NCsoft Store.
