(Updated 01/11/2026) MORTASHEEN, an original tabletop roleplaying world, is available to the public after over a decade of development

DIGITAL & PHYSICAL COPIES: KO-FI PHYSICAL COPIES ONLY: ETSY DIGITAL ONLY: ITCH.IO

More about this book and this game:

History of the project here

A condensed guide to the setting itself here

Expanding and co-managing a new tabletop gaming "brand" out of this setting is MY SOLE CAREER PROSPECT and potentially my entire new livelihood for the foreseeable future. This is literally now more than half my life's work.

If you can't afford such a LARGE AND CONTENT DENSE new gaming book (a fair chunk of the price is only the raw printing cost!) you can help me survive and get this life-consuming project off to a good start by signal boosting and spreading the word.

Miscellaneous Book Information:

Mortasheen is a monster-collecting setting I've developed for over twenty years, it has been in development as a tabletop roleplaying game for over fifteen years, and I have spent more than the last five years laboring on this first book alone. Credit to Morgan Mullins for the gameplay system, @gutsygills for every single playable monster build, rules expansion, testing and enormous amounts of other editing work.

Featuring guest artists including @biomechanicalmush, @sabedilemon, @iguanamouth and more

Softcover $60, Hardcover $70-80 (more on etsy to offset their fees) digital pdf download $40 so we have enough to split with the gameplay devs. Books may take 6 to 8 weeks or more to arrive after purchase, due to slow printing/shipping times and the amount of work I have to do on my end to pack them up and mail them out!

Backers of the original kickstarter are still receiving books as books finish printing and shipping to me (again, slow process!)

8 x 11'', 350 pages. Includes all rules and mechanics for running a campaign or playing in one, player biotypes, NPC's, locations, gadgets, lairs, setting culture, ecology, unique original battle system, story hooks, a secret antagonist faction for more epic life-or-death adventures and a modular ability system for modifying and creating any conceivable monster, object or phenomenon. All 177 monsters in the bestiary include detailed biology and characterization.

Free online-only playable bonus monster builds available on the front page of bogleech.com or at the bogleech.com/mortabook link, also all assembled by @gutsygills

I think my favorite creature from the Mortasheen book is these naturally evolved Mountain of Madness penguins who are just horrible little piranha dinosaurs. I’ll take ten.

Jokers are a really fun class, and this other big queen was a must for me to model.

Help a disabled, nonbinary Mortasheen editor facing homelessness

Donate to Support a Family Facing Eviction Crisis, organized by Caitlin Rips

This year has been rough on my family, with medical problems, car breakdowns, and… Caitlin Rips needs your support for Support a Family Faci

Vee @eeveeprincessxd may be known to some of you as a major contributor to Mortasheen by @bogleech, which has quickly become my favourite TTRPG. More importantly, they’re a part of a vibrant community that I love, and I have faith that this community will return the favour.

Vee and their family are in serious trouble. Their father works, but is on medical leave, so the family is without a major source of income. The numerous crises they’ve faced have kept them from making rent, so the family faces eviction.

As a queer disabled person who has faced homelessness myself, I can tell you Vee is experiencing something horrible that I wouldn’t wish upon anyone. Every single dollar will bring hope to them and their family.

From the link: “This year has been rough on my family, with medical problems, car breakdowns, and more making it hard to keep up with rent. Now, we're about to be evicted for non-payment, and lack the means to get the money ourselves. We've gone to all sort of social services for aid, but we either don't qualify, don't hear back, or get told that they're out of budget for the year. Please help keep us off the streets! We're running out of time and options.”

We’ve raised $1126 already. Let’s keep it going!

Please don’t leave Vee at the mercy of an unjust, ableist system. If you can’t donate, at least share this post so it reaches those who can.

Containing Demishade

Sheltage

Well, who else to start this psiclopedia than one of my own? After all, who couldn't appreciate the visual of a Sheltage chain, helping to observe the local populace? I mean, most people aren't like that Merrow who threw rocks at me the other day. I mean, who is to talk when I've seen them psilogging onto Bulbflash. You know that site is just empty posturing and politic-[RECORDING PAUSED]

Description:

This Demishade looks like a small bird cage whose “chain” is actually a tail ending in a stinger. They fly around using a round, ragged membrane that resembles fabric covering it at rest. 

Biology:

Only barely capable of movement when grounded, the Sheltage relies on flying with the membrane on its upper body, pulsing not unlike a jellyfish as it floats through the air. Its “cage” is made of a bonelike material, capable of surrounding and enclosing creatures smaller than it and harassing anything larger. If anything proves too resistant, the claw ending its tough and prehensile tail can inject a powerful sedative.

Behavior:

The Sheltage's main purpose seems to be the collection, analysis, and movement of retrofauna populations. They are often created in groups, working in tandem to ferry everything from roofrats to criwis to wherever the city needs them most. It isn't uncommon to see them before or after the scenes of a Wyworg's rampage, moving a portion of survivors to a place where they are less likely to cause damage. 

Due to their lack of combat prowess, Sheltages tend to be non-confrontational and polite, especially to anything larger than themselves. When among their own kind (or anything else they trust enough), however, they'll often be a lot more honest in their opinions. Due to this, the visual of multiple Sheltages hanging from their tails has sometimes been used as a symbol of gossipy and two-faced behavior.
