Some of these will likely become important in the next games, but are pretty mysterious in the first one.
Such things include the Leviathan of Dis, the Billionaire Volus Dig, and the various worlds with alien superstructures covering their surfaces.
Speak of the one's you found, what you think of them, and what importance you think they may have. Include sinister one's, like the "Monsters from the Id" carving. *shivers*http://masseffect.wikia.com/wiki/Junthor

What makes you think Junthor will have any importance in the sequels?

http://masseffect.wikia.com/wiki/Klencory Here's the bit about the billionaire.

I want to explore Junthor, and find out what the hell wiped those people out, If nothing else. IT'd be something fairly scary for Mass Effect.
Also, the Leviathan, and the crypts may be the key to wrecking the Reapers.

I think they're just background lore. If they were integral to the storyline they would probably be more prominent.

They could be interesting little nuggets that lead to something bigger...
Which, since Bioware has the manpower and the money, is completely possible.
What would happen if they WERE big elements to come in the series?

I think you probably have a better chance of finding hints and nuggets if you read the book(s?)...

*grumble*
I like speculation, m'kay?

I loved the neat little mysterious things on various planets in ME. Some that stood out are the moons orbiting one gas giant that were carved into the faces of a mysterious alien race, and another planet that was basically just a graveyard for another species. The ones you mentioned are cool, too. I think the one about the Volus billionaire may be important in later games - I mean, "machine devils"?

I want to see some race older than the Protheans, possibly these light beings, seek revenge on the Reapers. And that Leviathan, it's retrieval requiring a completely epic war with the Batarians, is the counter for the Reapers.

What planet was that graveyard? Faces?

Here's the man. Or the Vole.
You find some really weird stuff out there.
Like superstructures buried in the core of a gas giant.

Oh come on. I'm sure there's more.

Sorry, I don't remember the names of those planets.

Has anyone seen the Prothean orb that reveals some things about human evolution? You need to have the necklace that the Consort gives you to activate it. I can't remember the name of the plant but it is the one where you can rescue the scientist by killing a human, it's full of grass.
There is a giant orb and when you use the necklace with it you get a few pages of text. You see a Prothean ship through the eyes of a cave-man. You think it is a bird and are scared of it's "rumbling call"(engine). The Protheans observed the humans from their base on Mars. It brings up the question as to how much influence they had on our existence,

I'm thinking the Leviathan was Sovereign. After all, Saren didn't have it forever, it had to have been discovered first. At least, that's what I always assumed. I had never even considered it being the counter to the reapers, but thats a very interesting idea.

The book explains how Saren found Sovereign.

I always thought that "Monsters from the id" was a tongue-in-cheek reference to good old "Forbidden Planet"...

(For all you young'uns, it's a 1956 sci-fi movie starring Leslie Nielsen (yes, he of "The Naked Gun" and other spoof movies) loosely based on Shakespeare's "The Tempest", except ole Willie had no mentions of subconcious thoughts taking physical form and attacking. ("Id" was Freud's name for the human subconciousness.) At the very least you should recognize Robbie the Robot from that film. He's iconic.)
There! Who said you can't learn anything from discussing videogames? :)
