An Emerald Edge

Livia has a buyer for an emerald gladius. Mine the ore in the Gloam, smelt it, forge the blade, bring it back.

“The ore is in the Gloam, west of here. Smelt it, forge it, bring me the blade. I'll pay what the buyer pays, less nothing.”

Green rocks, two of them, in the Gloam. Then the furnace, then the anvil. Mind the highwaymen.
