Iskall needed iron. Badly.
And he knew that Mumbo probably wanted slime. But when the bouncy castle didn't receive any attention and Mumbo wasn't replying to his messages, well, he had to take a more aggressive approach.

By showing up to his house.

"Hey Mumbo?" He asked, calling out from the doorway before stepping inside.

And instantly, he knew something was wrong.

The tower of minecart chests was gone, bamboo growing rampant inside the build, vines from the jungle slowly covering the walls as if the trees were taking back the base that Mumbo had built.
A peek inside the chests revealed them to be mostly emptied of valuable resources (not like he was going to steal) and the tools the redstoner often used were gone as well.

He frowned, peering behind the portal and finding the tunnel Grian had painstakingly dug between his base and Mumbos- and naturally, Iskall followed it, finding a similar situation at Grians place. In fact, he hadn't heard anything from the prankster for a little over a week now- which meant that he was planning something or that something was seriously wrong.
Given the state of his base, Iskall guessed it was the latter.

He climbed his way out of the ruined hobbit hole and walked the short distance to Scars base. He was closest in proximity to the two- maybe he knew something.

"Scar? You there dude?" He called out. No response.
So he looked to Larry as if asking permission to enter (the snail blinked slowly and looked away) and Iskall took that as approval, scaling the ladder and stepping inside.

It looked normal at first, but something was off. Dust covered the workbench in the middle of the room and the curtains were drawn over the window, shutting out the sunlight.
"Scar?" He asked again, listening carefully for a response- which he received in the form of shifting covers above him.
Iskall followed the sound and found himself in the wizards bedroom.

It had a nice fireplace and a few shelves full of books and other trinkets, a staff placed haphazardly on the corner and about to topple over at any moment. Again, the curtains were pulled shut over the window here too and the fire was nothing more than a few dying embers.

But Scar himself. He was curled up in the bed, shaking. In the dim light, Iskall couldn't tell if it was from illness or silent sobs.

"Are you okay dude? What happened?" Iskall tried, to no avail. Scar barely acknowledged the fact that someone was with him, so out of it that reality felt like it was miles away.
"Is...kall?" He asked softly, his voice cracking.

"Yeah, it's me. What happened?"

Scar rolled over, turning away from his friend. "Go away."

"Not happening, dude. You need help, okay? Wait here, lemme get you some food." And with that, Iskall went back downstairs, throwing together rabbit stew before bringing it to Scar, opening the curtains as he went. "Eat this. You'll feel better."
And surprisingly, Scar sat up and ate, still silent, but progress was progress. He wasn't going to complain.

Scar set the bowl aside, pulling his knees up to his chest as he finally stared blankly at Iskall.

"Mind telling me what happened? Where's Grian and Mumbo?"
