Lore
Banshee-44 considered the relic on his workbench and the questions on his mind; one stood out above the rest: who were you meant for?

The form of the weapon suggested an oversized sidearm—a secondary weapon for a giant's hands. The function presented more so as an anti-material rifle. "Looks to be 12.7mm... it's like they were making a hand cannon but didn't know it yet."

Banshee wondered further about the warrior who could wield such a thing. His attention drifted momentarily, drawn by Shaxx's voice booming nearby. "Huh. Yeah. A Titan, maybe… and a big one too."

The weapon was laced with fractures from a life of fire and a sleep of ice, and perhaps other, more exotic stresses. Banshee wished he could've heard the relic's voice, but he knew from earlier examination that it had fired its last round. What a last round it must have been.

The Guardian who brought it to him might be willing to try a shot, untroubled by the risk of a rapid unplanned dismantle. But Banshee knew it wouldn't last through a single magazine.

Beside the relic lay a stripped-down Breechlight. He would adapt it for a larger round. Custom casings and handguard. Sensorium link scope… and he had other ideas to try as well.

It would be an homage, an offering to the creators of the original relic. A legacy.

With that satisfying thought in mind, the gunsmith went to work.

Trivia

 * Forerunner is based on the M6 magnums of Bungie's previous Halo series, specifically the M6D magnum of Halo: Combat Evolved that was well renowned as the most versatile weapon in the game. Appropriately, the weapon's lore and descriptions are full of Halo references.
 * The name of the weapon refers to Halo being the forerunner to Destiny, but also alludes to the alien Forerunners of Halo.
 * The Rock perk appears to refer to a quote by fan-favourite character Avery Johnson, where he jokes: "When I joined the Corps, we didn't have any fancy-shmancy tanks. We had sticks! Two sticks, and a rock for the whole platoon - and we had to share the rock!"
 * The use of a Breachlight as the basis for Forerunner is likely a nod to community members who previously used it as a stand-in for an M6 magnum when recreating the look of Halo's protagonist, John-117, better known as the Master Chief, on their Guardians.
