Between the Articles section and parts of the FAQ at the Citadel, we have covered a lot of the key historical information. Given this, here we will only point towards those sources, to avoid the need to update multiple pages when changes are made.
For information about more recent events, see the Recent History article. Please note that this article begins as pre-game history but then moves onto in-game history.
The in-game history began on the IC date of day 1 of month 1 in the year 158 AC. Everything after this date in the Recent History article is part of the history that has unfolded on the game, though it has been highly summarised.
