This hunter exotic was one of my first assignments at Bungie. Inspired by the Japanese gods of weather, Raijin and Fujin. Raijin, the god of thunder, lightning and storms and Fujin, the god of wind. I felt the lore behind these deities matched well with the perk mechanic of dodging and leaving behind an explosive.
A burst of wind followed by a clap of thunder.
I had this idea of hunters playing taiko drums, similar to Raijin's, as a way to warn other troops and it created an interesting narrative for me to work from. I imagined them scouting ahead of the group and sounding off their drums when they were ambushed. Warlocks, watching from afar, halting when they hear the drums, then witness the flash as Fallen Dregs fly outwardly through the air.
Of course, in-game, it's just a great way to deal with a Titan's shoulder charge. ￼
