Weapon Derivation: Y'know those pens with the different clickers for different colors?
Form 1: A larger-than-normal silver pen with 5 blue slide-buttons along the sides that each control a tube of concentrated frost Dust (in addition to the central ink-pen).
Holstered/Sheathed Appearance: They're pens. Kaltis keeps them stashed upon his person, at least three functional "Axioms" at any time. One of the most common places to see it is either tucked behind Kalt's ear, or tucked next to his notebook in the brim of his hat.
Features/Capabilities: Kaltis can click one of the ice-Dust chambers to activate the Dust inside and create a weapon (or other object) made of super-cold ice. He favours a lance, though has been known to pull a knife or sword instead in emergency situations. The ice weapon will last for as long as he has the Aura to keep it activated, or until it is melted by very high heat or shattered by a significant force.
Usage: Typically used as a lance/halberd, or as a dagger in emergency situations. Also used as a normal pen.
Planned/Possible Upgrades: Could be modified to handle different types of Dust
Notes: Kaltis is a cool-headed journalism-centric character who wants to know the truth behind every story, so I tried to give him a weapon to reflect that - cold, sharp, and to the point.
