A.R.C.H.I.E
A.R.C.H.I.E is a sentient construct made almost entirely out of polished steel, bronze and gold. Making him blindingly reflective on a sunny day, a fact that he seems entirely oblivious of. His metal form is also covered in arcane runes, which glow in different colors depending on what actions he is performing. Including his eyes, which often change color to represent what his internal units are processing.

Personality
According to his programming, A.R.C.H.I.E performs every task with the utmost zeal, attention and optimism. The latter of which can sometimes lead to his overestimation of other's capabilities, or lead him to perform a little more than asked.
Since his construction was never entirely completed, one of the elements left in development was his communication module. As such A.R.C.H.I.E speaks in a slightly stilted and robotic voice, often preferring figures and numbers rather than more understandable explanations.
Background
A.R.C.H.I.E (Automated Runic Companion for Humanoid Interaction and Engagement), is the pet project of the wizard Zinerva. Who constructed him as a part of her work in The Dekatia. However, his construction was derailed by a scandal and so he was never entirely finished and tested. Leading to some behavioral quirks which crop up at strange times. His purpose was to be a general purpose humanoid companion which people could give mental and physical tasks to in order to ease their own burdens.
