The shades of history

So I was just wondering about all of the things we dont know about the far history of tyria. And thought we could make a list of sorts and disscuss ideas.
Things like who lived there long ago and what they did (the seers, the mursaat, the giant titan people who's corpses are all over prophesise and so on)
How the world was created, i.e - did the gods really find the world and not create it? Who was there before, the dragons?
And other things like why were the canthans the first people on the planet?
Further more, why were the ritualists the first ever proffesion?

What else dont we know?

A list of these things would be wise to make, for those we know little to nothing about. But that list will be large, depending on how specific we go.

Discussing them, however, is pointless if we know so little about it. As we can say anything, and as long as it doesn't go against what we know, it has just as much say as saying that the Ancient Dragons will become our allies in GW2. <--won't happen, I'm highly sure, but it's an example of how "anything goes" with these topics.

If anything, this should be a list of things stay away from in discussion due to so little info on them. Of course, not meaning we should not talk about them at all.

Such things I can think about:
1) Giganticus Lupicus (the "giant titan people" you mentioned)
2) Ancient Dragons (despite what the Movement of the World states, we still know very little on them)
3) The Mage Lords (this includes Odran)
4) Origin of Dwayna, Melandru, Lyssa, Dhuum.

How do we know that Odran was a mage lord?

Technically, we don't. It is just assumed due to Odran always being called "Lord Odran" and he was a powerful mage - had to be due to making portals that went to the Rift.

We really do not know who was a Mage Lord, but there are several near concrete theories with nothing we know of going against it regarding the Mage Lords.

This thread basically summarizes all we know of and all we theorize about the Made Lords. Although the Mage Lords is not the topic of that thread.
