The Ether Light is a landmark in Xenoblade Chronicles. It is the central landmark and market in the Commercial District in Colony 9. There are many shops around, although only one will actually sell items to the party. This is a great place to start when looking to complete all 81 quests at Colony 9, since there are NPCs around at day and night.
These minor enemies are only found during the Mechon attack on Colony 9.
