So I'm somewhat addicted to this AU (not badly, I may write more shorts) by becca4leafclover (I think? Sorry for ping if not lol)

So this mainly focuses on Mumbo and Iskall and also Grian lol

— — —

Mumbo thought as he worked away. He was thinking about Grian's lack of appearance to them. The strawberry blonde would often fly in, but he'd soon leave out of discomfort. Mumbo couldn't understand why Iskall couldn't see it, because he himself could clearly. It was obvious to the point where Mumbo wanted to talk to him about it.

He would have to wait until later to do that, though.

First, the redstone.

Mumbo brushed off the excess dust from his hands and suit, and looked over at his friend. "Are you ready to test?" After his question was affirmed with a nod, they both hurriedly left where they were both working. Iskall stood by the lever.

"Three, two, one, Go!"

Iskall pushed the lever down.

Nothing.

Nothing happened.

Mumbo wanted to scream. "Are... Are you kidding me?"

"Mumbo, it's okay. We did something wrong, no problem!"

The sound of wings alerted them Grian had arrived, but Mumbo could've cared less. "I can't believe this! We spent ages on all of this redstone and it doesn't work?!"

"Woah! Guys, what's going on?" Grian rushed over to see what was wrong with his best friend. "Your usually the calmest member of Architechs, Mumbo, whats Up?"

"I'm so done! First we get these strange tattoos," he rolled up his sleeve to emphasise his tattoo. "and then Grian does a disappearing trick every damn time we try to meet up as a group!" Grian went red, glancing away.

As he did, he froze.

The redstone around the room was slowly lighting up, despite it clearly not working before.

"Mumbo, cal-"

"And now we've spent ages on Sahara, only to find it doesnt actually work?!"

As Mumbo continued ranting, Iskall finally became aware of the redstone. Parts of it sparked every now and then. "Mumbo! Please!" The Swede grabbed his best friend by the shoulders, staring into his glowing eyes.

Wait. Glowing?

Grian knew Mumbo's eyes were black with a mismatch of colours mixing in to make a beautiful array. But usually they were both this colour, not only the left one. The other was glowing a dangerous red, with markings going down the side of his cheek, darker than the eye colour itself.

Iskall held fast, but Mumbo panicked at being restrained like this, and pulled away. He then swung his arm in front of him, sending out a wave of red lightning.

As this happened, red thunder sounded throughout the server. The redstone around them sparked brighter than before, fizzling and burning out, before going grey. Mumbo grabbed at his chest and fell to his knees.

"Mumbo...?"

Grian's phone was getting spammed with notifications, but he was too focused on his friend. Mumbo looked up at him, his red eye fading back to the average colour, before he collapsed.

"Mumbo!" Iskall yelled, running forwards. He caught the moustached man before he fell completely. "Call X or someone!" The Swede was panicked, holding Mumbo up.

~~~

Grian: X get your butt over to Sahara

X: Why?

Joehillssays: What was that abnormal lightning?

Grian: Something happened with Mumbo. He freaked out because the redstone at Sahara didn't work and I think he had a minor panic attack?

Grian; I could be wrong, you'd have to ask Iskall, he was there when it started.

FalseSymmetry: Omg is Mumbo okay?

Grian: We dont know, he passed out

X: On my way there now, don't do anything stupid

Grian; Got it

~~~

"He jus.... red lightni... redstone, greyed out... strangely enough... unharmed..."

Mumbo's head pounded as voices faded in and out. He groaned, sitting up before grabbing his head, hissing in pain. "What happened...?"

"You've been out for a few hours, buddy. You freaked out over some redstone not working and caused the whole server's circuits to overload."

"What...?"

"Well, not all of it... but you should really be careful with these abilities. It seems to be tied with your emotions, so if they get too strong..." X trailed off. "So What is he Meant to do? Hide his feelings for the rest of time?" Grian asked sarcastically.

X hurriedly shook his head. "No, I'm not saying hide them! I'm saying... it's more of a case of watch out with them. If this was something minor like redstone not working, I'd hate to see what proper anger at a person would be like, or grief."

Mumbo looked down at his own hands, not sure wether to trust them.

"It's actually a miracle you didn't hit anyone with that lightning..." X hesitated before speaking. "We measured the energy levels and... if it hit a person it would have just insta-killed them."

"X, I don't think your helping."

Grian looked over at Mumbo as he spoke, and the poor man seemed so heartbroken. I mean, it showed he cared about hurting anyone, but still, it hurt Grian to see him that way.

"Thanks X..." Mumbo looked up and smiled.

Grian and Iskall saw through it.

~~~

Mumbo was at his base, feeling hopeless.

Stupid tattoos, stupid abilities, stupid redstone, stupid brain...

Stupid...

It was all stupid.

He was stupid? Mumbo sighed, before the sound of rockets and wings distracted him.

"Mumbo, we don't care what you say, we're gonna help you harness your abilities, got it? Yes? Good." Grian didn't give Mumbo any time to answer. Iskall facepalmed in the corner.

Mumbo smiled, this one was genuine. It didn't matter what his abilities did, or didn't do, he'd always have his fellow Architechs.
