In The Labyrinth, you encounter a Seraphim named Bomia. It seems that every couple of centuries she has to update the official maps of the area. The trouble is that the area is overrun with monsters and it is such a bother for her to carry all of the surveying equipment and kill all the monsters. She would like you to kill the monsters and clear the way for her to do the surveying.
The first monster is just to the south.
Go east over the bridge and turn south.
At this point, head south towards Crystal Cottages. You should find all the monsters you need to kill on the way. Once there, you will meet Bomia again.
So it seems this quest is not yet complete. Your first stop is back north, past where you started.
The next station is southwest of Crystal Cottages.
The third station is not so far. Just head straight north and you cannot miss it.
The final station is back in Crystal Cottages, just north of the Monolith.
Now to give the Seraphim the news and collect your reward. Just a little north of the last station, you will find Quitana.
