Every time I've run Lofwyr as GM, I treat him a bit like Victor Von Doom.
Arrogant, with an internally runaway ego but just intelligence and disciplined enough to not go completely mad with power.
He's the ruler the world needs, because he is a dragon, the best among all races, and the best among dragons.
The only "personal canon" change I make, is that he treats his most capable and devoted like favored pets (and everyone else as completely expendable pending failure). To him, it's not enough to just be feared and loved, they must know emphatically, philosophically, in their very soul he is sovereign.
He doesn't discern between Shadowrunners and wage slaves, because everyone who isn't his enemy is his tool in waiting...and even a few of his enemies are his unwitting tools and accomplices.
