First, congratulations on winning the fortress battle. It is a location of vital importance. Second, stop congratulating yourself on winning the battle--it is one of many.

Since you seemed so keen on capturing this particular fortress, I'm putting you in charge of defensive preparations. Better to tackle one problem at a time rather than wait for them to pile up.

That's where you come in. Clear out any Defense Hecklers in the area. Bring me back Burnt Ash once you've completed your task. Simple enough. Move!

Accept. Decline.

Unfortunate that we were rushed to action.

I'm sure you understand that force was the fastest way to deal with these potential interlopers.

Do you have anything to report?

"You were looking for this?"

Hmm, this is... interesting. Almost oily in consistency. Might be useful as an ignition catalyst.

I appreciate your work, Daeva. Not to be short, but I have other matters to attend to.

Please, take this as a reward for your time.

Completion:

Fortress Administrator Terenoa said that the area around the fortress must be cleared out in preparation for the next battle.

When you eradicated the Hecklers around the fortress and obtained Burnt Ash as proof for Terenoa, she gave you a reward.
