First step is to talk to Iruki-Waraki in Aht Urhgan Whitegate. He'll tell you about wanting to recover his Automaton that was stolen when he was watching two women one day in Aht Urhgan Whitegate. You can tell it's his Automaton because it acts unique although looks like a normal one. He asks you to go to Nashmau to look around and see if you can find the culprit. He also mentions that the person that saw it happen said it was a bald Hume
Destination: Nashmau NPC: Dnegan (H-6, second floor)
It's an island on the lake just outside of Nashmau. You can access the island from the east side of the lake by walking across a bridge of lily pads (green patches on the water). When you click on the ??? it spawns a NM called Caedarva Toad. Defeat it and check the ??? again for a cutscene. Note: There are two ???s at I-10. The one you want is in the center of the marsh, not on the outside.
