Terra's Pearl of Power

You are Terra, a woman in her mid-twenties. You have shoulder-length red hair and freckles to match, though mostly faded due to taking care of your skin. You're reasonably attractive, though single, and you have a B-cup bust and a fit bubble butt. No one would ever really say you've got big assets but it's not like you're exactly a stick. You are a nerd, or at least you were but now you don't have as much time to indulge in nerdy things. Except maybe once a week or two.

"Nat 20! It's a crit! He takes 69 damage!" You Scream. It was D&D night and she and her friends were all towards the end of a very long battle against a very strong BBEG, Big Bad Evil Guy. If they take out this guy it should be the end of their current game, meaning they will have to start a new one which could take weeks. Since they are all adults it's hard to schedule games around work anyways and they'd been waiting on this session for weeks.

Bobby, the GM, looks up from his stat block and says "That does it, with that last Chaos Bolt you scorch his chest and as his armor and body begin to go up in flames you have beat him. You have won." The table erupts in cheers and drinks, they've been at this particular campaign for upwards of 3 years and were finally done. It's a bittersweet feeling, on one hand they feel great they won but they also feel sad that their characters are now going into the post-game limbo of never being touched again.

You mention to Bobby "You know that pearl you gave me a while back saved me in more ways than one." "I'm aware," Bobby answered, "there was a plan for it too but it never came up then I just threw it away. It would've been too OP anyways." Now curious you ask "What was the plan for it? Was it going to be sentient or something?" "Not quite, kinda but not really. It was more or less get stronger the more you used it, allowing you to make your spells more powerful. I even had a plan that as it got stronger it let you use new spells or new innate abilities that could warp the world in your favor." You thought on that for a second and agreed "That would have been OP, fun, but OP."

The night was quickly coming to an end since half the group had to work early in the morning. Jill, the one that was playing the healer, and Kyle, who played the barbarian tank, both left together. The other 3 of you have been growing suspicious that they might be dating or something, but you're all friends so you figure they'll tell everyone when they are ready. Tim, the fighter, Bobby, and you spend another 10 minutes just hanging out and cleaning up before you feel it's time to head out as well.

It's a relatively short drive back home and you get there safely. After putting your stuff away and watching a couple of short videos on YouTube you decide to go to bed. The next morning starts as any other day you are off work, however, when you get up you notice there is a box that you didn't have before. It looks like a velvety jewelry box and it has a note on it. it reads "This gift is a Pearl of Power and can only be used by you, Terra. You will find that it can grant any wish you want, any alteration you want for the world, a person or people, or yourself. If crushed by someone else this power gets reverted and a new pearl will be given at any time of a week or a year later. If crushed by you the pearl's changes will be solidified and there's a small chance that you will gain the pearl's power without needing the pearl anymore. If you don't gain the power a new pearl will appear the next day and the world in this case will be considered the new default to revert to." You think this must be a prank from Bobby or someone, you open the box and it is a pearl, although a black one.
