This is the first "PvP only" zone of the game, it's only fair its daily quests are PvP oriented. Well 3 out of 4 is and they are nice and fast too. They are all available in the Fortress if your faction controls it or in your village close to the fortress if you're on offense:

• For 620 Honor and 20.63g you need to kill 20 Alliance Players. This is easily obtainable since you need to re-earn your Private, Corporal, First Lieutenant ranks at the beginning of each battle in order to control and buy siege engines.
• For another 620 Honor and 20.63g you have to kill 3 enemy Siege Engines. The big tanks.
• There are some fire elementals that are used to fuel the siege engines for 10 of their essences you get 412 Honor and 20.63g
• Of course there is a daily quest for winning the battle either by taking the fortress or defending it. The reward is another 620 Honor and 20.63g
