The lion-headed, steel-bodied Logan is one of the fiercest defenders of the Dawn Alliance.

One of the original Dawn Alliance founders, Logan could not be more different from his mostly academic colleagues. But what Logan lacks in refinement he makes up for in decisiveness; and what he lacks in gracefulness he makes up for with a fiery temperament that, as he puts it, gets results. But that is not to say he is a stranger to the ways of the scholar. Logan is one of the best engineers on the planet.

The steam-powered suit of armor that powers Logan across the tundra is also one of his own inventions—his gateway to a new life after a disabling injury. The mech is not exactly the most subtle of diplomatic instruments, but no one can deny the effectiveness of a metal fist when negotiations between the Dawn Alliance and less civil powers break down.

Logan plays the role of a kind of a "semi-vigilante" and "all-purpose guard" for the Dawn Alliance. Logan is the brute force solution: a walking tank in place of careful schemes. Whatever one might say of Logan's "often crazy" battle plans, consistent victory on the battlefield speaks for itself. The power suit grants Logan capabilities ordinary warriors can scarcely imagine.

Logan is no stranger to Phaethon, one of the Dawn Alliance's most implacable enemies. In fact, he was at one point made Lead Designer of Phaethon's daring Planetary Realignment Drive, which attempted to correct the Earth's course closer to the sun. It was Logan's good friend Bill who first opened his eyes to extraordinarily tragic human cost of the project. For the first time, Logan began to experience doubts about the end justifying the means. It was during this period of hesitation when Phaethon turned on Logan, removing his arm and almost his life. The Dawn Alliance rescued the grateful engineer. He quickly joined and swore himself to fixing the mistakes of his past.

Logan is not a man who spends much time in regret. "Talk is cheap" and "only action creates real change" from Logan's point of view. Logan's contributions to mankind are already immense. Even his worst enemies, those persuaded by Phaethon that his abandonment of the Planetary Alignment Project was unforgivable, are probably benefiting from the warmth of one of Logan's Furnaces. Logan’s masterful Furnace design has saved countless lives in the Great Chill, its design inspired by a Planetary Realignment Drive prototype. But no matter how many people Logan has helped, close friends often hear the same sad refrain from the bottom of another empty drink: "It doesn’t matter how much you do. You can’t bring back the dead."
