[D&D] How long has Asmodeus ruled the Nine Hells?

Yeah, I know there's many different interpretations of his origin but just saying. Has he been the supreme lord of the Hells since the very beginning? Or was he a relatively young (by devil standards) fiend that climbed the ranks and usurped the previous ruler of Hell?

Asmodeus is the one who made evil mortal. Before him there were evil beings in the Nine Hells, but they were the castoffs of creation, eldritch and unnamed by the gods in their paradise.

This garbage dump of the universe proved the ideal place for Asmodeus to consolidate his power, as he with the *consent* of the gods created a planar prison for mortal wrongdoers. And there he reshaped them all flesh and soul, the nameless things, the dead mortals, the plane itself.

Eventually, the gods took notice of how Asmodeus had perverted their bargain. They demanded his surrender. And that is when he pointed to the original contract of their deal, the first demonic pact from whom all others followed, and said:

*"Read the fine print."*
