Lore & Description

Appearance

The Clockwork Assassin is a sleek, metallic construct, with polished silver plating and intricate gears visible through small slots in its body. Its limbs end in sharp, retractable blades that glint ominously. Its glowing red eyes and a soft whirring sound emanate from within, giving it an eerie presence.

Behavior & Origins

Forged in the depths of the Arcane Forge, these constructs serve as relentless hunters for those who can afford their steep price. Their main directive is to complete their assassination contracts with deadly efficiency. Clockwork Assassins are often employed by shadowy guilds and nobles wishing to dispose of rivals quietly and neatly.
