Radia hasn't begun work because the ingredients that she ordered haven't been delivered yet. Visit Trader Varan and check on her delivery.

Varan says it is difficult to get the supply and he cannot deliver the order on the due date and asks for understanding.

Radia says she'll contact Ralford in the Ivory Tower in advance and asks you to get the materials from her.

Ralford doesn't have the items that Radia ordered, but she could get the spidersilk if she had some spinnerets. Go to the Sea of Spores and get 10 spinnerets.
