Orcus- Destroy the world?

[Sinistar]

Ok, so given the right set of tools, would Orcus want to destroy the world? I know some general info about the guy, but there is a lot of history for the demon that I only know through playing in a game. That has the potential to be heavily homebrewed, and I would like to start from a clean source.

So tell me out there you assembled Orcusphiles, what makes Orcus tick? Does he want to destroy the world, enslave mankind or just get bagels delivered every morning?

My plot is this: There are a series of planar gates in the Abyss. These gates lead from one level to the next highest level. They shift around a lot, but once every 10,000 years or so they all align so it is possible to step from the lowest directly to the prime material. That is still a good 5000 years away, but Orcus (if he so chose) has found a way to realign the gates and allow something to come directly very early. I was thinking of using the Armies of the Abyss -- Armageddon beast as my surprise.

But is this something that Orcus would do? As if he succeeds, the planet will be depopulated and probably cracked...
Any help would be appreciated.

If it would help him destroy demogorgan(did I got the name right?) he would. I'm using Orcus in my campain as well. He and Demogorgan have formed an (temporary) alliance and have as demonprinces overrun most of the devil realm. Now the devils have captured and used the great king of Erathia(that's the name of my realm) as a weapon against the demon-alliance. My party started out on an island of the daughter of the king and where informed the great king was captured. Erathia lies in chaos and Catherine, the daughter, now has send her army(about 5000 men) to bring back peace and find her father...well hope none of my PC's will read this so far...
