Grian watched Mumbo work, he decided to ask now as he didn't want to forget about the question again.
"Mumbo, why did everyone think you were a vampire?"
Mumbo looked up,"Oh? No one ever told you that story??", Grian shook his head,"Not really?", Mumbo put down his tools, it was time for his break anyway and what better way than to tell a story,"Well have a seat, cause it's time for a story.", Grian smiled as they sat down with drinks and snacks for their break.
"For context. . . My family is, what you would call very paranoid people to the point of how they would come up with any reason to not trust a family member, friends or even go outside sometimes.", Grian titled his head,"Really?", "Yeah, which lead to them never letting me outside of the house and I was homeschooled for my whole life, which resulted in me having very pale, flaky and damaged skin.", Grian oohed, now understanding,"So, people thought you were a vampire because of how pale you were?", Mumbo nods,"Yeah. . . When I was invited to Hermitcraft, I uh. . . Admittedly lied to my parents about it and ran away in a sense, and when I got to Hermitcraft I didn't talk to anyone much which made the theory much stronger that I was a vampire.", Mumbo looked at his hand, now his skin was healthy and had more colour in his skin than he had years ago.

=Years ago=

Mumbo stared at his work, he couldn't bring himself to continue as it felt like his feet were glued to the ground and his arms felt to heavy to move.
His eyes ached, he was tired and felt sick. . . Maybe he should go home, come clean to his parents and-
Knock
Knock
Knock
"Mumbo?"
The door opened, Iskall, Etho and Xisuma peaked in seeing one of their new members just standing there and staring at his machine.
Xisuma immediately recognised this; Burnout.
"Okay; Time for an intervention."
Mumbo felt someone take the tools away from him, then someone lead him outside and he was immediately above to move his arms once the sun beamed down on him,"Gosh. . .", "Sorry, you really need to get out more. . . We're worried about you, mate.", Mumbo looked at the three members, noting their concerns but it wasn't the faces his parents would have but. . . Something else, less extreme.

'After that, the others would make sure I would take breaks, get 3 meals a day, snacks, drinks and made sure I went out everyday.
Over time, I could see the difference in me from the past self; I had more energy, strength, I had more colour in my face, got better sleep and basically: I looked much healthier.
And I was socialising with others much better, it was like they possibly broke the cycle of my family shutin tradition.'
Mumbo smiled,"Rumors have gone away a bit about me being a vampire, though I think Scar still has his suspension.", Grian chuckled, of course Scar would.
