Made a full condition sheet for Firework’s right-side scars. I’ll post her full look–reference when it's finished.
(tap for better quality)
It wasn’t a small accident. That’s all you need to know.
Close-up below
–As you probably noticed, yes, I used Subspace's sheet as a guide to make Firework's one! Especially because of the perspective and it's the same arm lol, Credits to Sodakettle on Twitter/X for the og
That Subspace and Ban Hammer mini-comic but with my oc instead
I had planned to make a different panel with another perspective but I gave up

/Btw smt I should have clarified ever since I uploaded the relationship chart It's the fact that Subspace doesn't admire her, it's more like interest (not romantic bruh), except there wasn't a specific color for it idk. And as for Firework, she doesn't like Subspace because of his mere personality + the way he doesn't seem to respect boundaries (so no, the annoyance doesn't come from her knowing what happened between Med and him, as I suppose some might think).
Being a demideity and one of the handful who possess wings, I had to do this a while ago, so!
WING LORE & BREAKDOWN! ↓
The Weight & Lift Physics:
The Aerodynamics: Firework possesses a highly dense, muscular Inphernal frame weighing approx 110kg (240lbs). In standard aerodynamics, a heavy payload requires massive amounts of kinetic energy (flapping) to maintain altitude, which would completely drain a mortal’s stamina. So we got The Passive Soaring Solution! To offset her immense mass, her wings utilize a Passive Soaring profile rather than a high-frequency flapping model. The massive 8-9 meter span combined with a deep 1.5 meter chord creates a huge surface area that generates immense static lift.
Thermal Gliding: So Instead of actively fighting gravity, Firework uses her wings to catch thermal updrafts and air currents, allowing her to stay airborne and glide for hours with virtually zero muscle exertion! The separated, "fingered" primary feathers at the tips act as winglets, reducing drag and turbulence at low speeds so she remains perfectly stable while coasting.
Present-Day Utility:
The "Air Brake" Technique: Because of her high-density weight, falling from heights can be incredibly destructive to the ground beneath her. When landing or descending rapidly, Firework flares part of her massive wings completely open perpendicular to her path. The sudden, immense surface area acts like an instant parachute, trapping a massive volume of air and creating a powerful aerodynamic cushion that halts her heavy downward momentum for a gentle, controlled landing.
Propulsion Dashes: While she rarely engages in long-distance flying nowadays, she can violently snap her wings shut or flap them once with immense force to displace air instantly. This acts as a heavy kinetic propulsion boost, allowing her to dash quickly across a battlefield or launch herself into the air, though it burns througt a lot of sudden physical energy.
The Injury Factor & Nerve Damage:
The Patagium Trauma: Her right wing features a prominent, healed burn scars directly on the patagium, the leading skin membrane responsible for controlling the wing's aerodynamic tension and angle of attack. Because scar tissue is rigid and lacks the natural elasticity of healthy skin, this membrane cannot stretch or flex properly.
Asymmetrical Fatigue: When gliding or performing propulsion dashes, her right wing muscles have to work *twice* as hard to compensate for the stiff, unyielding scar tissue. This results in rapid fatigue on the right side.
The Lopsided Flight Path: Because her right wing tires out much faster than her healthy left wing, her steering can become slightly lopsided during extended flights. If she pushes herself too hard, she has a natural tendency to bank or drift slightly to the right as her strength flags.
Historical Backstory (8 Years Ago):
The Outward Journey: almost eight years ago, Firework used the full extent of her soaring capabilities to permanently flee from her family and her father, Venomshank.
Traveling the Desolate Wilds: So to escape their reach, she had to cover massive, punishing distances without being spotted. Her wings were her greatest asset during this era; by flying at extremely high altitudes where the air was cold and catching long-range wind currents, she was able to travel across entire territories undetected. It was a grueling test of endurance that permanently tested her limits before she finally found a place to settle down.
Tbh all this came to mind because of this Icedagger art, I'd would like if we got the other deities at some point to see if they have something like this too.
Alright since recently I’ve only shown a small sketch so far, here’s a proper introduction to Cinder and how they actually work in Firework’s lore. This will be like a Q&A section answering the basics to understand this little creature;
↓
Q: Who (or what) is Cinder?
A: Cinder is a bird-like companion that has been with Firework since the moment she spawned. They are not a pet, not gear, and not something she “found” later—they are intrinsically tied to her existence. The easiest way to understand it is: Cinder is an externalized part of Firework that can exist independently. Most of the time, Cinder takes the form of a small bird inspired by a bird-of-paradise—bright, elegant, and expressive. Around others, especially in Playground, this is all people see: just a strange but harmless companion that follows her around.
But that’s only the surface.
Q: So… are they “just a sidekick”?
A: No.
Cinder behaves like one—perching nearby, reacting to things, moving on its own—but that independence is only partial. It mirrors Firework’s emotional state very closely, sometimes even before she shows it herself. It’s not just following her; it’s aligned with her.
Q: How do the wings work?
A: Firework does not have permanent, visible wings. Instead, when needed, Cinder fuses with her. This isn’t symbolic or metaphorical—it’s literal.
Cinder’s body breaks apart into energy and structure, merging into Firework and reforming as a pair of wings extending from her back. During this state, they are no longer two separate entities. They function as a single being.
These wings are temporary, can be partially or fully manifested, can be used in short bursts (mobility, stabilization, impact control), or fully extended in more extreme situations
Most of the time, Firework only uses small, almost unnoticeable fragments of this fusion—so subtle that others (like Shark Shooter) don’t even realize what’s happening.
Q: Does this happen often?
A: Not really.
Firework is capable of fusing with Cinder at will, but she deliberately limits it. In her current life, like i said, she mostly uses: brief, merges like small “buff-like” enhancements, also like quick defensive or movement adjustments.
Full wing manifestation is rare. Especially now.
Q: What’s the difference between Cinder and Sisyphus?
A: Both are bird companions tied to divine beings, but they function very differently.
Sisyphus (Venomshank): Acts as an external extension—scouting, observing, accompanying. He represents Venomshank’s “wings”, but remains separate. As the Wiki itself says: "Sisyphus is Venomshank's wings, as opposed to having an actual pair on his back."
Cinder (Firework): Is an internal extension that can become external—or reintegrate completely. When Cinder fuses, it becomes Firework’s wings. There is no separation during that state.
Q: Are there risks?
A: Yes. Because Cinder and Firework are linked: an overuse strains both of them, unstable emotional states affect fusion quality, losing control can pull Cinder into that instability.
For example; during "The Day the Sky Broke", Cinder was pushed back their limits during a massive, uncontrolled fusion and entered a near-inert state for hours afterward—completely drained.
That moment is a big reason why Firework is so careful now.
Q: Why hasn’t this been obvious until now?
A: Because Firework hides it. She avoids full manifestations in front of others and keeps fusion subtle and controlled. To most people, Cinder just looks like a companion—nothing more.
That’s completely intentional.
Q: So what is Cinder, really?
A: Not just a bird. Not just a power.
Cinder is a constant presence tied to Firework since she was a newspawn, a stabilizer when things go wrong, something that reflects her, protects her, and when needed becomes part of her.
Sooo in summary; Cinder feels what Firework feels, It means overuse affects both of them. And it means that when Firework loses control (like, goes feral), Cinder is pulled into that state with her; sometimes stabilizing, sometimes being pushed past their limits. (Like i said “The Day the Sky Broke” is the only known time Cinder fully burned out after a fusion, collapsing into a near-inert state for hours.)
Outside of fusion, Cinder is expressive, restless, and closely attuned to Firework’s emotions, often mirroring them before she even shows them outwardly. Around others Cinder behaves just independently enough to pass as “just a bird.” Well they aren’t.
