Lore in Oblivion refers to the background story of civilizations, gods and heroes of Tamriel, spanning over millennia. Mods try to enrich the Lore, complete it and in many cases, simply ignore it and focus on improving the game itself.
Modder giskard (via the renamed Engineeing Guild) has been working on expanding on the Lore with several extraordinarily detailed mods :
– Kvatch Aftermath
– The Origin of the Mages Guild
– The Necromancer
– Fighters Guild contracts
– The Elder Council and its Temple of the One add-on.
These mods are essential improvements to storylines dropped by Bethesda during the course of making the game.
