Silent, but deadly

Jemmot Wolkhart revealed a potential breakthrough in ranged weapons technology: a non-arcane, silent air gun that packs a punch like a harquebus. The missing key to his design was the Blast Harmonizer, lent out to the party back on Althena for testing purposes. Using it a little too roughly, the item got damaged, but patched up by Gok.
  Helping Jemmot out could net them a silent and deadly weapon, extremely useful for someone like Zerkorn. However, protecting his inventions is no Jemmot's strong suit. In the industrial district of Danaï, there's always someone ready to poach another's idea's. In fact, that is Brennik Groathammer's entire MO.
