In the quiet of the night, beneath the earth so deep
There's a world of monsters, where secrets they keep
A fallen child, lost in a realm of dreams
Where love and hope are more than they seem
Through the Ruins, past the pain and fear
Meeting friends and foes, both far and near
Toriel's warmth, like a mother's embrace
Guiding the way, in this hidden place
Heart of the Underground, where souls intertwine
In this world of shadows, the light will always shine
With every step you take, with every choice you make
Love and mercy are the bonds you won't forsake
Papyrus' laughter, and his brother's silent gaze
In Snowdin's chill, we find our ways
Undyne's courage, burning bright and true
Fighting for justice, for a future anew
Alphys' heart, hidden yet so kind
In her lab of secrets, hope you will find
Mettaton's glam, shining in the dark
Dreams and ambitions, ignite a spark
Heart of the Underground, where souls intertwine
In this world of shadows, the light will always shine
With every step you take, with every choice you make
Love and mercy are the bonds you won't forsake
Asriel's sorrow, the pain of the past
In the garden of memories, love will last
Flowey's remorse, the desire to change
In the heart of forgiveness, nothing is strange
In the end, it's not about might
But the kindness you show, in the darkest night
A world reborn, from a single soul
In the tapestry of fate, we find our role
Heart of the Underground, where souls intertwine
In this world of shadows, the light will always shine
With every step you take, with every choice you make
Love and mercy are the bonds you won't forsake
So remember, dear child, in the depths so wide
In the heart of the Underground, love will abide
Together we'll stand, through joy and strife
In Undertale, we find the meaning of life.
