|3700 Gald | Crown Feather|
Talk to Leia near the Talys Highroad exit and then enter the Fractured Dimension No. F421C.
Although the portal takes you straight to Bermia Gorge you can actually exit into Culmar Trail, which is adviced if you want the two treasures there.
Head east from the entrance and continue all the way to the dead end and enter the hole to the north for 3700 Gald and then backtrack to the fork. To the north is a circle with a east and west path, but you want to hug the west wall as you head north to find the second treasure in a hole for a Crown Feather .
There is no point to head back to Sharilton, as there are no treasures or new store items offered.
