Observer

An Observer is a quest item from Fallout 3 given to the player from Moira Brown during the quest: The Wasteland Survival Guide. Moira asks the player to place the Ovserver in one of the 3 batches of Mirelurk Eggs to observe their behaviour. You must then travel to the Anchorage Memorial to do so.
