Bethesda is holding a charity auction that could allow you to create your very own character to appear in The Elder Scrolls VI, with all proceeds from the auction going to the Make-a-Wish Foundation.
In an announcement post on its website, Bethesda says the winner of the auction will get "the opportunity to work with Bethesda Game Studios to create a character to appear as an NPC in The Elder Scrolls VI".
All money made from the auction will go directly to Make-a-Wish, and the auction is open to anyone in the United States, although you'll probably want to have a fair bit of cash handy if you're planning to bid.

At time of writing, current bidding stands at a whopping $11,650, so you're going to have to bid over that if you want to create your own Elder Scrolls VI character. Still, at least everything is going to charity!
Of course, it is worth noting that The Elder Scrolls VI currently doesn't have a release window; in fact, we know very little about the game, beyond the fact that it's presumably still in development and that it probably won't release until next year or later.
It's also worth noting that Bethesda doesn't provide any kind of time frame in its post, so it could be a while before you're invited to collaborate with the studio to make your own Elder Scrolls VI character.
Again, though, all of the proceeds for the bid are going to charity, so if you've got a lot of money knocking around and you're looking to spend it on a good cause, you could do a heck of a lot worse than this.
The Elder Scrolls VI was first announced all the way back in 2018, and since then, Bethesda has been relatively radio-silent regarding the game.
We still don't know where it will be set or what the story will be, nor do we know what to expect with regards to gameplay (although we can guess it'll be a first-person RPG along the lines of its predecessors).
If you'd like to bid on the character creation auction, you can do so by heading over to the Make-a-Wish Foundation's Silent Auction page and searching for "Bethesda", where you'll find an opportunity to contribute. Alternatively, you can make a flat, non-Bethesda-related donation here.
