The gods that swallow us whole
Prologue:
To humans, the walls had no meaning. Perhaps they had, ages ago, numerous centuries ago, thousands, thousands of years ago.
Rumor says they stood intact to this day, in order to complete one purpose, to protect humans from some grotesque danger that's looming outside. Now, a couple of thousands of years later, the walls held a purpose completely opposing that of its early times. Instead of keeping the danger out, they were keeping people in.
They lived pleasantly, bathing in luxury within those walls.
Word also got around, those walls have been breached, broken, pulled up and built anew right from the wreckage of war.
And now they stood, beyond reach, beyond destruction, beyond the spoiling hand of living beings, coated with hard metal, rising upwards, the walls of humans measuring full 4 thousand feet of height. Those who lost faith in superior forces, in spiritual beings, they worshipped the walls.
And humans, they built cities inside the walls. They made buildings of glass, standing tall and powerful, speaking legions of glory, yet never competing with that of the walls. Humans rode rolling vehicles, flying jets soaring the skies, but they never dared fly out of their territory, beyond the walls. They feared the unknown and they rejoiced in what they had.
The day the walls fell, humans received a grim reminder, a morbid insight on what lay out there. The day those humanoid creatures, reaching thousands of feet up high, peaking above the walls themselves, humans understood why they've lost faith in the gods.
Because the gods walked the earths and turned everything to rubble.
Because the gods had no mercy.
Because the gods swallowed us whole.
That was the day Eren found himself homeless, motherless.
He no longer had anything, save Annie.
