How could we have managed to lose Siel's Western Fortress?! I thought we had everything covered!

We must recover it! We must!

• "Okay, we will. Calm down."

I can't calm down! This is too important to approach calmly!

Look, we need to strike at their defences. That's the only way to win the fortress back!

Will you help, Daeva?

• Accept.
• Decline.

The best time to attack is when the Asmodians have control--they're much easier to fight than the Balaur. There will be a battle during the Vulnerable State.

You must go to the fortress then and wipe out the Siel's Western Fortress Garrison--Asmodian Fighters, Asmodian Archers, Asmodian Mages, and Asmodian Priests. It doesn't matter if they are Veterans, Experienced or Novices.

Bring back their Fortress Insignias, too. Please, hurry! We must get control back as soon as possible!

• "I'm on it."

You must strike a blow on the Asmodians that have taken Siel's Western Fortress. When the fortress is in the Vulnerable State and a battle is under way, defeat the enemy garrison and return with the Insignias of Fortress.

Daeva! You're back!

Did you defeat the Siel's Western Fortress Garrison? And bring back the Fortress Insignia?

• "Yes, here."

You haven't gone yet?! You don't understand the danger we face!

Go to Siel's Western Fortress when it is in the Vulnerable State and defeat the Siel's Western Fortress Garrison! Return with the Fortress Insignia!

Quickly, quickly, go go go!

• "I'll be back."

Oh! Oh thank the many blessings of Ariel, you've defeated them and brought the insignias, just as you promised.

Oh, it should be much easier to take back the fortress now. Thank you, Daeva. Thank you so much.

Liber said that in order to recapture the Siel's Western Fortress, a significant blow must be inflicted on the enemy using a small force and asked you to defeat the Asmodian garrison defending the fortress.

So after defeating the Asmodian fighters, archers, mages and priests, you returned to Liber with their Insignias.
