Arcanus would be in his workshop, concocting a rather deadly arsenal for Helios, having made his 173rd Dreadnaught, the Panzer line of robots were designed for total control and dominance.  Once he heard the conversation between Tyler and Aetius cease, he chimed in.  "Sir, I have made another 23 Dreadnaughts, 134 assault bots, 214 scout bots, and 200 infantry bots.  All ground units.  Though, I have some ideas about the new air units that RnD and I talked about.  I'm sure you'll love these new additions to your robot army." he says, his voice always modulated by his suit, and let's face it, he rarely ever left that suit, only leaving it to perform... necessary... body functions.  It was heavily armed and armored, should he ever be sent out in the field, but for the most part, he relished working on adding new bots to the ranks of the robot army.

Of course, he wanted to go out in the field.  He wanted to test out his suit in combat for the first time, but right now, he was content to add to his ever growing collection of "pets."
