Titan's end (AU)
Tragic AU in which the Skibidis succeed in killing an Alliance Titan… causing an absolute ecological disaster, instantly wiping out the skibidi platoon that felled the Titan and making any gains for the Skibidis a hollow pyrrhic victory. The Titan's death causes its core reactor to melt down and explode violently, killing all life in the vicinity from the shockwave and heat and blast radius of irradiated razor-sharp shrapnel. All the Titan's various coolants and lubricants and other fluids pour out and render the land barren and inhospitable to plant life for decades.
No Skibidi can go anywhere near where the Titan fell. But the inorganic Alliance aren't affected (except emotionally), and build a new base on the site of the Titan's death - of great emotional (perhaps even spiritual) significance and of great strategic importance. Here is where the best of us fell. And still they protect us, even in death.
To the Skibidis the message is clear: you took something precious from us, but you cursed yourselves by destroying your own forces and giving us a place where you cannot touch us and which serves as a rallying beacon for us. And soon we will rain down every agony imaginable upon you.
