Founded in 1991 almost by accident by Ben "Gryphon" Hutchins and the individual known only as "[=MegaZone=]", Eyrie Productions Unlimited is the writers' collective responsible for the classic MegaCrossover FanFic ''UndocumentedFeatures'', along with a half-dozen or so other works (all on a somewhat smaller scale). They are particularly infamous among a segment of ''Anime/NeonGenesisEvangelion'' fandom for their anti-nihilistic reconstruction of ''NGE'', ''NeonExodusEvangelion''.

Their trademarks include a free-wheeling style liberally laced with pop-culture references, an optimistic approach to their plots and worlds, a tremendous amount of imagination applied to dovetailing the various elements of their story universes, and -- perhaps most importantly -- the shameless use of [[SelfInsertFic self-insert characters]] (although this last is by no means a constant throughout all their fics).

Their website (and thus all their work) can be found [[http://www.eyrie-productions.com here]].

Over the past two decades, the membership of EPU has varied as the demands of college, work, and real life have swelled and ebbed for the various members. The full list of current and past members, taken directly from the EPU website, is as follows:

* Derek Bacon (deceased) (UF)(NXE)
* Janice "Ardaniel" Barlow (UF)
* Chad "Wedge" Collier (UF)
* Anne "Juniper" Cross (UF)
* Geoff "Mephron" Depew (UF)
* Benjamin D. "Gryphon" Hutchins (UF)(GW)(TIA)(WL)(HL)
* Adam "Pfloyd" Johnson (retired) (UF)
* Rob "[=ReRob=]" Mandeville (retired) (UF)
* Larry "R-Type" Mann (UF) (WL)
* Chris "Mako" Meadows (retired) (UF)
* [=MegaZone=] (UF)(GW)(TIA)(WL)(HL)
* Dave Menard (missing in action) (Staff artist)
* Phil Moyer (Staff artist)
* Pearson "Doc" Mui (retired)
* Kris "Redneck" Overstreet (retired) (UF)
* Rich "Rat" Pieri (retired) (GW)
* James "Mechaman" Rinehart (retired)
* Martin [="PCHammer"=] Rose (UF)
* John "Truss" Trussell (UF)(NXE)

UF = ''UndocumentedFeatures''\\
NXE = ''NeonExodusEvangelion''\\
TIA = ''[[http://www.eyrie-productions.com/TIA Bubblegum Crisis: The Iron Age]]''\\
WL = ''[[http://www.eyrie-productions.com/WL Street Fighter: Warrior's Legacy]]''\\
HL = ''[[http://www.eyrie-productions.com/HL Hopelessly Lost]]''\\
GW = ''[[http://www.eyrie-productions.com/GW Gods Willing]]''

(The abbreviations in parentheses after each name indicate in which projects a particular contributor has an avatar character. It is safe to assume that if the contributor has an avatar, he has also contributed to the development or writing of that setting; even if no avatar is listed, he has probably contributed to ''Undocumented Features'' in some way. The only exception to this coding is the late Derek Bacon, who contributed only to the early development of the ''UF'' setting (reputedly producing a large document of notes which the current writing team apparently still consults). His avatars in both ''UF'' and ''NeonExodusEvangelion'' are posthumous memorials to his influence on the lives and writing of the core members of EPU.)

Various members of the EPU collective also have solo efforts to their names, such as Gryphon's FilmNoir-styled ''TabletopGame/InNomine'' story series ''[[http://www.eyrie-productions.com/45 .45 Caliber Angel]]''. Many of these can be found at or [[http://www.eyrie-productions.com/ETC/related.html linked off the EPU website.]]
