That's Your Spark is an original song from the TrueDark Rising world. It belongs to the settled era of Farshadow, when the Orders govern daily life and every person at sixteen must choose the craft that defines their place in society.
The song speaks to young Kinsfolk approaching their Spark -- the moment of choosing an Order. Some rise early and walk the shore. Some mark the field by sun and rain. Some feel the grain in standing trees. Some shape the clay, some set the stone. The chorus names the truth the elders pass down: a spark makes itself known not by shouting but by what pulls you back when work is hard, where you return without regard. That's your spark. Name it true. Not what you wish -- but what calls you.
The final chorus lifts the stakes. Keep that spark through work and years. Through steady hands our light appears. We shape a light that holds its place. And some, through cost and patient sight, will burn their spark into True Light. That's Your Spark remembers that the Orders were not merely bureaucracy -- they were the Kinsfolk's way of carrying the Keepers' gifts forward without repeating their costs.
Like all songs of this world, it serves as memory. It is meant to be sung at the choosing ceremony, and understood fully only in hindsight.
