Thundercoil
Last updated 2026-07-16

Thundercoil is an NPC on Planarcadia, located in Duomension City and Desolate Maw's Demonhold.
Profile
Thundercoil is an imagenae that resembles a serpent dragon. It surrounds the Seafeld TV Tower and powers the city. After the IPC took over Planarcadia, it also works for the Planarcadia Broadcasting and Television Administration Bureau.
The thundercoils are historically great strangelings that have crossed the boundary of "impossibility" and manifested into reality, already at the absolute limit of what an imagenae core can sustain.[2] In this day and age, ancient strangelings like thundercoils can no longer be brought into existence.
The Thundercoil is highly protective of local traditions and domestic Planarcadian brands. Anyone who drinks foreign beverages, such as mung bean soda, in front of it will be struck by its lightning.[3]

Dialogue
- (First interaction)
- ???: ███▄████▀▄▄▄█▄█▄▀▄█▀▄▄█▄█▄█▄▀▄▄▄
- A suspicious phone booth, ringing with crisp, clear chimes. When you curiously pick up the receiver, there is no greeting, no apology, no accusation, no sales pitch. Just a surge of electrical current that instantly pierces through your mind. Your eardrums buzz and ring.
Is the phone busted?
Is this some kind of prank?
Is this an indiscriminate attack?
Could this be an urban myth?
Could it be you?- You never know. In Planarcadia, there's nothing that's impossible to see.
- In fact, that's exactly how Wishpower works: you could even imagine a surreal control panel, adjusting the ambient volume to protect yourself from attacks by the lingering spirits of past Phantasmoon Games contestants...
- ...Hey, wait, listen! Within that chaotic noise, there seems to be some kind of logic, some kind of voice...

- A string of unfamiliar names surfaced through the crackling static. There was definitely someone, or something, on the other end of the line. He recited them. She was searching for them. Its voice was oppressive and cold, as if dragging a rusty hospital bed through a morgue.
Who is he?
Who is she?
Who is it?
Who are they?- You're completely clueless, or maybe drowning in too many clues. The list keeps growing. Ten, a hundred, a thousand, ten thousand. He's searching for them, but why? If she's still alive, what connection do they share? And if it's already gone, then...
- The lifeless white noise is gradually breeding a strange, dark conspiracy in the cramped phone booth. Cold sweat. A chill. The sky darkens. Is the Phantasmoon still up in the sky? Is it watching? Watching where? Them? Him? Her? It? You? Me?
- ???: █▄▄▄█▄██▄████▀▄▄▄▄█▄▄▄█▄█▄▀▄█▀▄▄█▄█▄█▄▀▄▄▄
- Again. Sharp. Deep. Shrill. Dense. Hoarse. Abrupt. Grotesque. Muffled. Whispers. Closer. Getting closer. He's nearby. She's there. It's looking for you. He found you. She's by your side. It's about to speak...
- ???: █▄▄█▀▄█Above is this month's sacrifice reserve list▄█▄▀▄▄█
- ???: █According to the Planarcadia Broadcasting Management Regulations, ▄█the aforementioned individuals must submit this month's required sacrifices or Wishbaes▄▀▄within the deadline to the TV Tower▄to the Great Strangeling Thundercoil▀▄█
- ???: ██▄▀...shouldn't it be the former Great Strangeling?▄▀▄Whatever, everyone will get it anyway▄▄█let's just leave it at that█▄█▄██
- ???: █Anyway▄▀▄█This month's Planarcadia Broadcasting and Television Administration viewing fee collection notice has concluded█▄█▀beep-dong-bong-dong█▄██
What?- ???: █▄█What's so surprising about that?█▄█▀That's the brilliant business strategy of the Planarcadia Broadcasting and Television Administration Bureau!▄▀▄*A burst of electrifying laughter*█▄█▀▄▄
- ???: █I am the Great Strangeling, Thundercoil█▄Even as I was reading the broadcast script█▀I had already noticed you█▄▄▄
- ???: █▄▀If you're curious, ask away▄▀▄█consider it keeping this old relic company▄█▄██

- (Subsequent interactions)
- Thundercoil: █We meet again▀▄▀▄*A burst of electrifying laughter*█▄█How about keeping this old-timer company and passing the time with a little chat?▀▄▄
I'm wondering...
You're Thundercoil?
- Thundercoil: █▄That's right▄▀▄As you can see, this old soul is the big guy perched atop the TV tower▄A great strangeling in every sense of the word█
- Thundercoil: ▄██Right now, I'm communicating with you through the phone line█▄▀If you'd like, we could switch to a TV instead▄█▀▄▄
- Thundercoil: ▄██But don't forget to pay this month's viewing fee!▄█*A burst of electrifying laughter*▀▄▄▀▄█
What's your connection to the Broadcasting Bureau?
- Thundercoil: █▄Once comrades-in-arms▄partners▀▄guardians██Now? It's a business relationship▄█▄██
- Thundercoil: █▄Oh, don't get me wrong▀my feelings toward humans remain unchanged▄█▄█For a great strangeling like me█talks of money don't hurt my feelings█▀▄█
- Thundercoil: The IPC brought sweeping change to our World in Canvas. The ▄█Faekind Protection Act granted all imagenae the same legal and social rights as humans. We now have the right to work▄ run businesses, and participate in politics just like anyone else█▀▄█.
- Thundercoil: Of course, ▄█many imagenae were reluctant to lower themselves at first, myself█ included. But to obtain enough Wishpower▄█ to survive, we had to embrace change▄█ and build the future▄█ with our own hands. Ironically, this brought us closer to understanding█ human joys and sorrows█▀█▄.
- Thundercoil: I remember▄ when they had to wine and dine me just to keep the city powered█▀▄. Now look at me██, busting my butt brainstorming commercial TV shows to keep the audience entertained▄█.
- Thundercoil: The times are rolling forward█▄, and the relationship between humans and imagenae shouldn't be limited to just one form█▄! *A burst of electrifying laughter*██
What's a great strangeling?
- Thundercoil: ▄██A so-called great strangeling▀█▄▄is an imagenae that has crossed the boundary of "impossibility"█▄▄▀█and manifested into reality▀▄▄
- Thundercoil: In this day and age█▄█▄█ancient strangelings like me▀█▄can no longer be brought into existence▄██▄██The reason is simple▀▄█Humanity has stopped believing in their creation█▄▄
- Thundercoil: ▀▄█Isn't it laughable?█▄▀█▄▀When people no longer believe in their own creation█▀█▄█▀█▄they can no longer create▀▄█What absurdity▄█ *a burst of electrifying laughter*▀▄▄
Thanks. I don't have any more questions.
- Thundercoil: ▄▀Farewell, and enjoy today's television programs▄█If you'd like to chat with this old coot again, you know where to find me▀▄█*A burst of electrifying laughter*▀▄▄
