Great to see that a fan group of Papyrus exist
I grew up with the comics and really love them, now I'm watching the tv series.
I'm currently writing a fanfiction, which I started several years ago but didn't continue. It's called "Seth" and you can find it on Fanfiction.net and AO3. But it's a continuation of the comics, so it does also have some spoilers for those who haven't read them.
Also for those who would like to read the comics, cinebook did recently publish their 7th English translation (Album 22 Sekhmet's Captive).
