Set in a reimagined Transformers Prime Universe, A Shadow Between Sparks continues the war-battered Autobots' story after the destruction of their base back in Jasper, Nevada. Forced into relocation, they now establish in Fort Sentinel Bastion, hidden deep within the watchful peak of Mount Vigilance, Colorado.
For five years, the Autobots experienced a rare season of peace, until circumstances and curiosity unsettled their fragile calm. When Ratchet and Wheeljack uncover fragments of strange evidence tied to Halo Quartz, a mech whose very existence raises questions older than Cybertron's wars, suspicion and unease begin to spread through the ranks.
What begins as playful banter and late-night discoveries soon twists into something heavier: trust falters, shadows lengthen, and secrets embedded in glyphs and relics may unravel the Autobots from within.
This fanfiction reshapes Transformers Prime into a tale of hidden truths, fragile bonds, and the fine line between light and shadow, where even the brightest sparks may conceal the darkest secrets.
