Mass Effect Wiki is great for looking up anything about characters, places and events from the games. But their book and comic summaries are questionable, and the science often inaccurate.
The most reliable source of information is the Codex, which consists of ingame encyclopedic entries.
The official ME site is good for pictures, news, and ads.
Mass Effect 1, Mass Effect 2 and Mass Effect 3 as movies. It’s a male Shepard with a different background from what I play and write and possibly very different choices during important missions, but it’s more than illustrative. Probably the best way to learn about ME short of playing the games themselves.
An enlightening interview with the voice actors (especially part 2 and what Fred Tatasciore – who played Saren – has to say about the character).

Fanfiction stuff:

Here’s a list of fanfiction I like. But be warned: much of it is NSFW, so watch the tags.
I post my stories here, on FanFiction.Net, on deviantArt, and on Archive of Our Own. For NSFW things, consult the list above.
My partners in crime (who will hopefully excuse my awkward complimenting), are, in order of appearance:
- Misfire Anon, who not only writes beautiful stories about Saren and Nihlus, but also draws beautiful pictures.
- Inthenightside, who writes wonderful AU stories about Saren, a female Shepard and Nihlus in various combinations.
- Logsig, who writes fantastic slash stories about an irresistible male Shepard with Garrus, Kaidan, and occasionally other characters.
Special thanks go to:
- Anjian, for Signal to Noise.
