Lightship
From PAdventures.info
One day, for unknown reasons, the group of magnemites, which was driving the light in the lighthouse stopped producing electricity. Yenni thinks, that when you bring her 30 Magnets everything will return to normal state.
magnets drop from magnemites and magnetons. The easiest way is to go to the power plant under Lavender.
Yenni will reward you for magnets with 55hd.
