The Ambassadors, Dead Gods crucified by the Skies... "composed of the same dusty, needle-thin material as Night Witches. They levitate across Axis Braven and are infamously identifiable by their “W” shaped wings, large enough to be spotted in the Sky from miles away" (p. 168). #ttrpg #art #noai

An Ambassador, giant levitating monstrosities covered in Nightly hairs, looms above, as a Gorestorm begins nearby...

"Being a Scientist means being your party’s powerhouse of information and innovation. You will take the world around you and mold it to your whim by customizing Items and copying the abilities of monsters you encounter." Download the #ttrpg THUNDERFORT for free! thunderfort.itch.io/thunderfort-...

A depiction of a Thunderfort character (an Ape-kin) whose Class is Scientist. She is small and thin figure, but her immense wisdom shows; she carries several scrolls and an old-fashion counting frame (and, of course, she's wearing a big pair of glasses!)

Another depiction of the same Scientist character; this time, she is operating a huge, bipedal mecha, though it isn't made of metal but rather of biological scraps, bones, and limbs harvested from various fantastical monstrosities.

As well, a text blurb states "Create your Scientist!

Another text blurb is a description of the "Creature Craft" feat in Thunderfort:
"Upon finishing a Laboratory Project, you can activate this Feat. Doing so lets you record the Project’s feat on this Feat, rather than your “Laboratory” feat. If this Feat has a recorded Feat on it, you can activate this Feat as a Fort Action to create a special Invention: rather than combining two Items, choose one Item to “combine” with your recorded Feat. While equipped, this Invention grants its user your recorded Feat.
You can only ever have one Invention made via “Creature Craft” at a time. The above effects can be repeated to make a new “Creature Craft” Invention, but doing so destroys any 'Creature Craft' Inventions you’ve already made."

"Being an Artist means being the backbone of your fort’s sense of hope, brightest when the world goes darkest.

A depiction of a Thunderfort character (a Beetle-kin) whose Class is Artist. She is a tall, four-armed arthropod with herculean beetle horns, and she plays a large mandolin.

Another depiction of the same Artist character; this time, her mandolin playing is summoning a ghostly white cloud. Within the cloud, a trio of skeletal, undead humanoid lizards raise their swords, ready for battle! As well, a text blurb states "Create your Artist!

Another text blurb is a description of the "Spinner's Song" feat in Thunderfort:
"As a Full-Round Action, while having a Musical Instrument equipped, you can activate this Feat. Make an Artistry roll using your instrument. You may then use your result to play one of the following songs...
Song of Blood: for 10 minutes, all allies that can hear you become Invigorated and gain an amount of Blessed stacks equal to your Artistry result divided by 10, rounded up.
Song of Bones: for 10 minutes, all allies that can hear you gain an amount of Temporary Health equal to your Artistry result divided by 5, rounded up.
Song of Souls: at the end of this action and until the end of the day, you summon a number of Dead Kin Warrior creatures equal to your Artistry result divided by 10, rounded up. These Creatures spawn in any unoccupied space(s) of your choosing within 30 ft. of you.
This Feat has one usage and recharges after an hour of Rest, or at the end of the week."

Cannibalism is a high crime in the Age Above; a heinous act that amplifies the suffrage of going eyes up, our inevitable fate. Yet, many still partake. There is great, horrible power to be had from eating eyes: the pearls of the Soul. New #ttrpg: thunderfort.itch.io/thunderfort-public-playtest-ed

A GOUGER: a creature from Thunderfort. This humanoid wolf monstrosity has hundreds of eyes growing out its mouth, tongue and throat; a hallmark mutation wrought by consuming the eyes of those who die in the Age Above.

The Gouger's creature sheet, with all its statistics and special features.
