[Help]Why can't I find any mission?

I am at 17 level, but I can't find any mission to do now. The last mission I got is at Beacon's Pench, after that I can't get any mission from NPCs although I went through all the cities I visited before. Yesterday, I spent 2k to ask a guy to take to Droknar's Forage, but he said that one mission will take me to there later. And also I can't find any mission in Droks. Can any one help me?

The towns I visitied are:

Ascalon City
Serenity Temple
Froontier Gate
Piken Square
Yak's Bend
Beacon's Pench

The quests I have done are:

Ruins of Surmia
The Great Northern Wall
Fort Ranik
Nolani Academy
Borlis Pass
The Frost Gate

Please help me. Thank you.

Wow, Lvl 17 and not even at Lion's Arch yet. You got to fight to Kryta from Beacon's or get a run to Droknar's. From there you can do Ice Caves of Sorrow. There is a quest in Kryta that will take you to Lion's Arch to continue the storyline.

btw, the things you call quests are the actual missions, and quests are stuff you can just do outdoors ^^

One of the NPCs in Beacon's Perch will give you the quest "To Kryta: Refugees", which takes you to the next mission.

As someone previously stated, you have your quests and missions terms mixed up. Great Wall, Surmia, and Nolani, etc, are all MISSIONS. Quests are the assignments you get from NPCs with ! over their head.

I swear half of the new people in Beacon's Perch get lost because of that stupid quest. After you finish, To Kryta: Refugees, the NPC tells you to go after Aidan in the ice caves. However, since there is no arrow pointing that way many people just think the quest is over and head back to beacon's perch. There should be a linking quest somewhere in between.

Seriously, buy the Prima guide.Even if outdated it's still very usefull.
