Hmm. At over 100 words, your blurb is a little long. Not hugely so, but it behooves you to shave a few words. Thoughts as they come.
***Arwyn has just bought Fantasia, the first fantasy-based VRMMORPG, with 99% realism that you can play while you sleep. In the game, she becomes Fey, a moon elf starting in the magical Elvenwood.***
Disney's gonna sue. No, but in all seriousness, never a good idea to name a fictional location (at least, any important one) after anything real world, famous, and owned by a major company. You can get away with naming things after real people/locations "New America", "USS Oprah", or what have you- that's fine (and potentially an awesome hook- I know I'd read a scifi story where Oprah somehow got a space ship named after her, if only for curiosity's sake)- but avoid anything with someone else's brand recognition being on your front page.
For a similar reason, you may want to reconsider naming your character Arwyn. Yes, I know it's a real name, but it also either is, or is pronounced like, a couple rather famous fictional character names.
Drop the words "exciting" and "hilarious". They're basically buzzwords which have been abused so much by "professional" media to promote garbage that by this point anyone who sees the words have an instinctive aversion to them. At least, when the author is making such claims.
Let OTHER people call your work exciting or hilarious or the like. You want to use words like "misadventures"- which implies excitement and comedy, but doesn't make such a bold, arguably arrogant, claim at success. Plus those words have been reduced to buzzwords, which makes them generic and boring now.
Too much spent on the "magical creature" thing. You can drop the word "menagerie" in there and strip pretty much the whole second half of the sentence. Repetitiveness is generally very bad in a blurb (I know, I broke that rule in mine, but I broke it to accomplish a goal I considered more important).
And the end lines need to go. Especially the "see if you figure it out first" part. Breaking the immersion by talking directly to the audience is a high level literary technique that takes perfect execution to pull off. Or a story that's pure comedy. No one complains about the lack of internal consistency in Monty Python. You've got neither.
Since you want to do snarky narrator... I'd suggest converting the final line to
"(PS- No, the NPCs aren't self aware AIs. I checked.)"
It's short- which is always a good thing. It sets up the narrator as snarky rather than just makes a claim. It tells the reader to pay attention without going full Navi on them.
You can change the "I checked" to something else if you like. "The author's not that clever", as an example. Or "On a related note, does anyone know a good civil litigation lawyer?"- depends on how mean spirited or self deprecating the snark is gonna be.
You also really do need establish some motivation of the main character since you put focus on her in the first paragraph then seemingly forgot about her for the second half. I can't help you there, since I have no idea what that motivation is.
