probably a lot of this is just that i dont have very good eyesight these days (+ sit reasonably far from the screen, low brightness for comfort, higher res screen so the same pixel size looks smaller), so a lot of stuff looks nice, but when formatted as grey on black it gets hard to follow
Undergrowth (Yongasabi: igonda) is an anthro Rain World AU, told as a hybrid webcomic and askblog. While the Endless Winter of Saint's time rage outside, slugcats and scavengers have long been forced to change their lifestyles, with most moving into geothermal pockets underground. In this setting, the timeline is compressed, events overlap, and in the warmth of Undergrowth, Saint maintains a garden shelter where they house the other slugcats.
The blog author is @opashoo. If you have any questions that aren't addressed directly towards Undergrowth or its characters, you can ask me at my personal blog. Ko-fi here if you're feeling generous.
Content Warning: As of now, Undergrowth is a +15 work. The exact nature of subject matter will be subject to change as I feel out the tone, but it will contain depictions of trauma, blood, injury, and sexual themes. This blog is generally aimed towards an adult audience and posts will be tagged appropriately.
Blog context, ask rules, additional info, and table of contents for the blog's chapters below. This post may change as time goes on.
Rules
As of June 1st 2026
Asks are generally handled diegetically, communicated through overseers as a means of long-distance communication. Asks can be fun and playful, but I won't be entertaining things like Magic!Anons, spam, bait, or nonsensical asks. DMs to this blog will be ignored.
Asks should generally be directed towards specific characters. Be sure to address the character you are speaking to. Asks that don't address anyone specific will be up for grabs by any of the characters.
If you have a meta question, or want to ask a question non-diegetically, please include "[Meta]" at the beginning. If the ask is unrelated to the blog, or you just want to send an ask to me directly, my blog is @opashoo.
Unfortunately I won't be able or willing to answer all asks. I'm ultimately doing this for fun and will prioritize telling a story, so asks will generally be slow or closed during story events. However, the breaks between story events are generally the designated time for asks.
No slurs. You can be rude to the characters if it makes sense for the context, and you can even look up some Yongasabi insults if you want, but no real life slurs.
When it comes down to it, I run the blog and I get the final say what gets posted.
Context
The story as it stands
The Undergrowth AU is an anthro AU where the blizzards of Saint's timeline have come sooner and deadlier, forcing most Yongasabi (slugcats) and Mulngjer (scavengers) to settle in underground geothermal pockets or adopt lifestyles suited to the cold. It takes the timeline of the game and compresses it so that all slugcats are alive concurrently, and all the events of the game have already happened much more quickly, oftentimes overlapping.
Pebbles' collapse and Moon's acquisition of the rarefaction cell are recent events. The Metropolis Scavengers have moved underground to found New Metropolis; Artificer's rampage and subsequent exile are still fresh in the minds of the both scavengers and slugcats; the worsening blizzards prevent travel between retaining walls. Hunter—whose condition is dependent on active treatment from NSH—Rivulet, and Spearmaster are trapped in Moon and Pebbles' retaining wall while Monk, Survivor, and Gourmand have all been separated from their colony. Everyone lives in a shelter built in Undergrowth, run by Saint.
The AU centers around Saint after the events of their campaign, who has taken to the teachings of Rhinestones Beneath Shattered Glass and started a garden in Undergrowth, where they have gathered all the other slugcats to live in safety. The other slugcats see Saint as a mysterious benefactor who knows more than they should, rescued each of them from certain death for unknown reasons, and given them shelter from the blizzards, but for Saint, it's all part of a comfortable routine formed from countless lifetimes of repetition.
In their most recent lifetime, however, things have started to change. Things aren't where they should be. People aren't where they should be when they should be. Events that have always fallen on consistent times and dates simply don't. Then Saint starts getting dream visits from someone they've never met before in all their past lifetimes, one who brings ominous warnings about the future.

The language
I developed the Rain World conlang Yongasabi for Undergrowth, so you may see slugcats occasionally using words and phrases from it. You can find it here.

I have officially opened my webcomic/askblog 🎉Developing Undergrowth has been a big undertaking for me, and actually drawing and publishing it will be even bigger, but I am both excited and anxious to start. I'm shooting to update weekly, wish me luck!
