After obtaining this treasure, go up the stairs nearby and slowly make your way to the room in the center.
Approaching it will automatically teleport us elsewhere. Upon arrival, look back; there is a Dust mote.
Save at the checkpoint before setting off.
Walk onto the wooden platform ahead; the wall on the right is climbable. Normally, you need to press Space twice, but it's fine if you fall the second time. Follow the path on the right to pick up the item there.
After climbing up, there's a Dust mote on the carriage to the left.
Continue up the stairs; there's also an item on the left.
After picking it up, head to the right. There's another Dust mote between the crates.
After crossing the bridge, you can talk to the person on the left, and there's an item to pick up ahead.
Head down for more items, and you can spot another purple one ahead.
Continue forward. On the left is Memory Flower #6 of "Frost Blade," and on the right is a purple item.
