Intro and Masterlist
Howdy! I’m River! If you’d like, you can also call me Glacier or Mako (pronounced May-ko; like the shark species).
What do I write?
I write character x reader. Currently I only have writing for the Markiplier egos and characters, very little for the Jacksepticeye egos, and Tenna from Deltarune, but I may dabble in writing other characters (Starlo from Undertale Yellow, for example).
I’m most comfortable writing SFW. I may occasionally write something suggestive, and I’ll label it as such. If I try writing NSFW, it’ll likely only be on my AO3. I’ll post a link here. Reader is gender neutral by default and I’ll specify when they aren’t. All romance is adult x adult. I don’t really write smoking because it makes me uncomfortable.
Other accounts?
Here on Tumblr, I have two other blogs. @gaymingintrovert is my main blog and @gaymingartist is my art blog (which I rarely use). I also have a selfship blog where I reblog suggestive/NSFW things so that one is 18+ (@gaymingselfship).
I also have an AO3 account where my newer writing will be (“newer” meaning anything from May 8, 2025 and onward since that’s when I made the account).
Requests?
As of now at least, I’ll only take headcanon requests. I may take a little while to respond and finish requests, so please be patient. Headcanons are less formal than a full writing, so expect a looser format than my more formal writing. Feel free to also just ramble about anything I’ve written or other ideas in my inbox if you’d like.
