It was never implied that you died before the traveler was discovered, but that you died before the darkness defeated the traveler. The guardians were an order established before the darkness arrived. All in all the warlocks would be considered the newest order among the guardians. It can then be theorized that when the darkness arrived people started fleeing and some of the guardians left with them. While fleeing they changed, and upon realizing this they sent scouts out to see the situation on earth and your character probably died in all the fighting. At least that's the way I imagined it going down as an awoken.
