{{Quote|Observe. Connect. Conceal. Conform. Comply. Return.|The Odysseus Protocol}}
The '''Department of External Observation''', or '''DEO''' for short, was a United States task force charged with investigating extraterrestrial anomalies throughout [[Earth]].

==Overview==
The DEO is responsible for investigating and making contact with extraterrestrial life forms. Employees at the DEO are trained on following the Odysseus Protocol, a type of protocol that is enacted in an event of abduction by those life forms. When the Odysseus Protocol is active, they must observe, connect, conceal, conform, comply and return.<ref>'''Bungie (2025/7/15)''', ''[[Destiny 2]]: [[The Edge of Fate]] - Item Description: [[Eunoia#Lore|Eunoia]]''</ref> The DEO also studies concepts such as pangeometry and strange matter.<ref>'''[[Timelost DEO Documents]]''', ''[[Timelost DEO Documents#03|03]]''</ref> Reports sent by the DEO are then sent to the U.S. Pentagon for evaluation.<ref name="MP"/> The DEO's HQ is found in Chicago, Illinois.

==History==
{{Stub|section=yes}}
The DEO was established prior to the Golden Age, though the exact date of its formation remains a mystery. The DEO was involved in investigating an unknown energy weapon linked to the death of John F. Kennedy<ref>'''Timelost DEO Documents''', ''[[Timelost DEO Documents#07|07]]''</ref><ref>'''Timelost DEO Documents''', ''[[Timelost DEO Documents#08|08]]''</ref> and was the department responsible for an investigation into the Les Diablerets incident.<ref name="MP">'''Bungie (2025/7/15)''', ''Destiny 2: The Edge of Fate - Item Description: [[Melas Panoplia#Lore|Melas Panoplia]]''</ref> During those times, William Moffat was the Director of the DEO. The DEO would submit a report documenting the movement of a spherical object in deep space, which was labeled "X0192", which was later known as the [[The Traveler|Traveler]], and predicted its estimated arrival into the [[Sol System]] to be fifty to sixty years.<ref>'''Timelost DEO Documents''', ''[[Timelost DEO Documents#13|13]]''</ref> The DEO would then spearhead Project Graviton, with its end product being the [[Graviton Spike]], and Dr. Nella Davis was a mathematician who worked for the project.<ref>'''Bungie (2025/7/15)''', ''Destiny 2: The Edge of Fate - [[Declassification]]''</ref> Another one of its employees, a linguist named Louis Yero, began experiencing strange dreams while he was working at the DEO<ref>'''Timelost DEO Documents''', ''[[Timelost DEO Documents#09|09]]''</ref><ref>'''Timelost DEO Documents''', ''[[Timelost DEO Documents#10|10]]''</ref><ref>'''Timelost DEO Documents''', ''[[Timelost DEO Documents#11|11]]''</ref> until one day, he went into the DEO's containment room and answered a phone of unknown origin<ref>'''Bungie (2025/7/15)''', ''Destiny 2: The Edge of Fate - Item Description: [[Graviton Spike#Lore|Graviton Spike]]''</ref>. What he didn't know was that the [[The Nine|Nine]] were the ones sending him the strange dream before he was then pulled forward in time.<ref>'''Bungie (2025/7/15)''', ''Destiny 2: The Edge of Fate - Item Description: [[The Edge of Fate (quest)#Step 12|The Edge of Fate: Step 12]]''</ref>

==Trivia==
*The DEO resembles several fictional clandestine government agencies depicted in films, games and works of literature, such as the [[Wikipedia:SCP Foundation|SCP Foundation]], the Federal Bureau of Control from the 2019 game [[Wikipedia:Control_(video_game)|Control]], and the titular organization from the [[Wikipedia:Men in Black (film series)| Men in Black]] series.
*The DEO's investigation into the Lee Diaberets incident is similar to the U.S. government's investigation of the 1947 Roswell incident.
