Why don't you collect it yourself?

I'll help the merchants.

Write your name when prompted.

Step 2: Pay the one-time fee of 50,000 zeny. The agent will teleport you to the quarantined area of the Sograt Desert.

Step 3: Walk east and talk to the cat. Choose:

Let's do this!

The cat will teleport you to the Dimensional Gorge.

Step 4: Walk north and talk to the Cat Paw Agent. Choose:

To the other world!
