A/N: Hi. Chapter time. I'm very happy with all the positive comments I've gotten from the Fulgora art. It helps a lot to see how much people are enjoying the story. Thanks for your patience.
My shopping trip with Thea and Castalia doesn't have many stops after we exit Costco. The main thing I need that I couldn't track down there is a proper sewing kit to turn some of these outfits tail-appropriate, a process that is surprisingly involved. Fortunately, a ...

Is wishing with all your soul that you were someone else the same as yearning for death?

A/N: I'm... drained. Sorry for all the messy schedule issues lately. Life remains challenging. The end is not yet in sight. But I'll get through it, and we'll be back to normal someday. Thank you all for your patience.

A/N: HI I'M BACK!!! FOR REAL THIS TIME! Sorry I missed another chapter of this. I had to, uh, evacuate my house for a bit last week? So that cut into productivity a lot. Good news is my house and my stuff and everything is okay!!! So yeah. Hopefully that's not going to happen again. Uh. So yeah!!! Enjoy the chapter.

A/N: Hello! Apologies for missing the last AYEH chapter. The situation here hasn't changed yet, unfortunately... but more specifically, I missed it because there was a wildfire right next to my house and I had to evacuate, which sort of took up an entire day. Next week though, barring yet more acts of god! Next week for sure! Oh, and one more thing. Content warning: suicidal ideation. Content promise: this one's pretty gay. Enjoy the chapter!

A/N: Happy new year, everyone. I'm back! Sorry it's been a whole month since the last AYEH chapter. Things have been rough, and it took me a while to feel functional again, but the rest did me well and I'm doing much better now. With luck, the external stressors will be done soon as well. In the meantime, please enjoy the chapter!

A/N: Hello, everyone! To those of you who read AYEH, I'd like to thank you for your patience. The extra time has helped me a lot with deciding where I want the story to go, and I think it will benefit a lot from the short break. AYEH will return at the end of this month. To the rest of you... here's the MGMH chapter you've been waiting for! I'll be honest, I was originally planning to jump right into a Fulgora perspective, but I just got so many messages begging for a bit longer to co...

You know, as someone who doesn't actually celebrate any of the winter holidays, I was not expecting this holiday season to be so overwhelmingly stressful. But life has had different plans.
A while back, a friend of an acquaintance I know found herself unexpectedly homeless. I happen to live somewhat nearby, and I also happen to believe that all human beings have a fundamental right to safe shelter, so we have been assisting her temporarily while she arranges for a more permanent reside...

A/N: Hehe hoho chapter time! This is the first chapter of volume 3! Enjoy!
The raw shock of Thea, of all people, ordering me to stay silent about my own obligate slavery short-circuits my thought processes. Figuratively speaking, of course. The crystalline components that pass for my circuits are fine, it's just… what am I supposed to say? What am I supposed to do?

We're only halfway done with the story as a whole, but damn if that isn't an important milestone.

Apologies, but due to some recent Life Events™ I'm not going to be able to write AYEH this week. I'll have an AYEH chapter written next week instead (which would normally be my break week).
Apologies for the wait.

Get your hotdogs, get your meatballs, get your stromboli, and make sure you're in a mentally healthy place for this, because it's going to be a looooong chapter.

Content warning for... eh, this isn't really much a spoiler. It's a Luna chapter in the current situation, so suicidal ideation and hopelessness are prevalent. By the by, we're probably about 2-3 chapters away from the end of volume 2. I am so very excited! Oh, and as a final note, we have one transformation...
