Riddle #1

Who/What am I? I bear an old name. I am born of those who died to protect. I am of the future-glimpser, the flood-watcher. I leave joy and suffering in my wake. My very form reveals the struggle of my existence. After all, there is no higher power then I. Edit: I wanted to throw this out there before I get too many guesses. You [i]must[/i] explain your answer. The correct answer with a poor explanation will be counted as [b]wrong[/b]! Congratulations! As you probably all know by now, yes the answer is the Gjallarhorn. Good job xTrainerYellowx for guessing it first, and congrats to EagleEye and FTG Griffix for stellar explanations! But this is just the beginning, guardians...
