Essence of theUnderworld

You become master of the Underworld, the keeper of all that is imprisoned and bound to that wretched place. While in the Underworld you are immortal and invincible to anything can freely teleport anywhere within the Underworld. If you are somehow killed you will resurrect in your palace after a day has passed.

Have a palace at the center of the Underworld filled with all the luxuries you could ever ask for. Inside of it there is a throne room and while sitting upon this throne you have an omnipresent view of the Underworld and can see through or control any being trapped in the Underworld.

You can detect, manipulate, or conjure any element found in the earth from the earth in massive amounts particularly metals. Additionally you are strong and durable enough to survive brawling with the likes of Hekatonkheires and drag them to the underworld.

Can open doors to the Underworld anywhere you care to, whether it be to conjure massive doors or crack the earth in two to open the pits up. Permanent gates can be established if you want others to be able to come and go, you can lock down these gates at will.

Have the ability to summon infinite amounts of indestructible profane chains in a variety of ways. These chains can be used to restrain the gods and pin them down, they suppress any powers or abilities and will drain them if left attached for too long. The chains can be used to drag any targets into the Underworld and trap them there for eternity, similarly they can be used to target souls. Powers will return if the chains are removed long enough though anything summoned will have all of their power until they are returned to confinement. You can manifest other objects on the ends of any chain like daggers, claws, or beartraps.

The inhabitants of the Underworld are bound to your commands and cannot rebel or twist the spirit of any order given. Any soul that is not automatically taken to a specific afterlife or destroyed outright will wind up down in the Underworld. Copies of objects, vehicles, ships, or even cities can end up sinking into the Underworld if there is enough death involved in their destruction or loss. You may have your Underworld filled with anything that meets these prerequisites up to the point when you first arrive in a setting or take one loaded down with the legends and history from your world. Either way it is a lot of souls and treasure.

You can summon anything that has been subjugated to the Underworld by opening a door to the Underworld and calling them forth. If killed the damned being will be pulled back into the Underworld and be resurrected right back into wherever where they were interned. No matter the method used the profane chains will never fail to drag them back to the Underworld even if they manage to get to another realm.
