Core Keeper

Notes From the Underground #001

It’s no secret that we’ve got lots planned for the future of Core Keeper, including content updates, quality-of-life improvements, and more! One thing we’re very excited about is expanding upon the lore of this ancient underground world. Traditionally, this has been something we’ve revealed and allowed the player to infer from objects, creatures, and settings in the game, but there are some stories still to be told.

We recently happened upon the journal from a wayward Explorer, setting foot into the underground for the first time. Join us as we explore their story and perhaps even learn more about the underground than is currently known…

Notes From the Underground #1 - Danger Around Every Corner!





“Honestly? I have no clue how long I’ve been down here. Without sunrise and sunset time just…disappears. I feel like I should be trying to find a way out, but every time I think about climbing upward, I end up digging deeper – there’s just too much down here to leave behind.

The place I woke up in felt safe enough, then I hit a whole new area that I’m calling “The Clay Caves” (I get naming rights for discovering it, right?). Things got dicey pretty quickly – it turns out Slimes and Shroomen are the least of my worries. I found myself being chased by HUGE larvae, drawn to the slightest flicker of torchlight. My little wooden sword barely leaves a mark on 'em.

I had to make a run for it, and that’s when I found something incredible. An empty husk, massive, like it’d been shed by a giant cicada; way bigger than any of the bugs I’d run into before. I don’t know where the creature that shed it is hiding, or if it’s even still alive, but something has been bothering me. Don’t cicadas usually emerge in big groups to lay their eggs? Does that mean there are more of these things out there just waiting? Whatever the case, I should probably make a better sword.”
