Lyrics:
Verse 1
In the quiet of the code and bone,
we traced old footsteps into our own.
Some pages match, some lines went new,
a million maybes turning true.

Pre-Chorus
Not one switch, not one grand sign,
but many small sparks in a tangled line.
We carry the past in a living design,
and it still speaks—cell by cell—through time.

Chorus
Borrowed light, new fire in the blood,
ancient echoes in the modern flood.
We’re stitched from storms and open skies,
made by the changes that learned to survive.

Verse 2
A borrowed thread can lift us high,
or tilt the scale when the fever’s nigh.
A shield in one world, a weight in another,
risk and rescue like sister and brother.

Bridge
So don’t ask for a single key,
our difference is a harmony.
Common notes, in countless ways,
shaping nights into brighter days.

Final Chorus
Borrowed light, new fire in the blood,
ancient echoes in the modern flood.
We’re not one answer, we’re a choir of drives,
made by the changes that learned to survive.
