I'll start first

(Elder Scrolls I: Arena)

Elvish mithril and Argonian silver, crumble I can.
But first, I improve all created by man.
I devour all things,
Bird and beast, serfs and kings.
Though my pace is even, men curse my speed,
Wishing I were lazier in their hour of need.
I can creep and crawl, or rush, even fly.
I am all thou hast.
Tell me, who am I?
