You get your own fortified Stronghold, which exists outside the bounds of time, space, and even reality. This renders it beyond the reach of most anyone, and even those that do reach it will find that it's protected by an impenetrable field. Only those that you allow will be able to enter.
*Any currency you gain is automatically sent to a vault inside the Stronghold, and you can call it back any time you wish. The vault will grow larger as you collect more money, so you'll never run out of room to store your money. Different currencies go into different vaults, to keep things nice and orderly.
*Any weapons and armor you gain are stored in an armory, and organized neatly. You can "switch" weapons and armor in and out at will, with clothes going to their own place.
*You gain a table with a terrain map of the last region you were in before entering the Stronghold. It shows any major cities, landmarks, and points of interest. It also shows any real estate you have in those locations. It also shows the locations of any mission you have.
*You get a wardrobe room, where any clothes, beards, hairstyles, makeup, and tattoos you've had are stored, and where you can wear them again. No, it doesn't make sense for some of those things, but this is an extrauniversal living space, which is debatably more odd.
*Any furniture you buy/steal/otherwise gain are stored in a basement storage area, and can be applied to any room in the Stronghold.
*While in this stronghold, all aging is halted, will not have any basic needs, and no longer grow ill.
*You can change the default aesthetic of the stronghold, which is a posh medieval castle, to any other theme you wish.
*The Stronghold, being the extraversal place it is, can take you anywhere in the multiverse. It can insert itself into these places, or open a literal doorway there.
*If you wish, the Stronghold may become sapient, and can generate servants to handle various tasks, such as cleaning, cooking, and other miscellaneous things. The Stronghold is unwaveringly loyal to you, and nothing can influence it otherwise. The Stronghold can also generate an avatar of its own, or take over the body of one of the servants.
