He's got the NEEC, and by extension most of Europe, in his pocket.
He's been ruling over what is now Germany since he beat up Almaise and kicked him out way back in the Second World. That's a long time.
He might have had some eggs stashed somewhere in Tir Tairngire before he lost his seat on the Council of Princes. (They probably were not his biologically, however... adult dragons mate and then give their eggs to a great dragon to raise. But they'll probably take after him more than their biological parents, anyway, thanks to dragon telepathy.) They've almost certainly been moved.
I'm not entirely sure if he's the loremaster or not. When I played through Survival of the Fittest, Hestaby won the contest to become loremaster. But I've seen several sourcebooks saying that Lofwyr is. (Maybe the game's writers just assumed that the players would turn on Hestaby when Lofwyr offered them more money, and my group was an oddity.) If so, he's sort of an odd choice. The previous two Loremasters (Dunkelzhan and his predecessor, Vasdenjas from Earthdawn) were both basically polar opposites of Lofwyr: they put forth the image of being approachable (Dunkelzhan had his trid show, while Vasdenjas authored several books for the Library of Throal) and relatively friendly and willing to share their knowledge (within certain limits), and both died in an act of self-sacrifice. If Lofwyr were the Loremaster, I'd be concerned that he might abuse the position.
According to Street Legends, his Magic stat is only 27... not as high as you'd expect from a Great Dragon. Hestaby's is 36. Harlequin has a 30. Again, I wonder what that says about his qualifications for the Loremaster position. In terms of influence in metahuman affairs, of course, controlling the biggest megacorp puts him way ahead of anyone (save perhaps the twenty minutes or so where Dunkelzhan was president).
He might sometimes use the name Hans Brackhaus for his human disguises. A lot of Saeder-Krupp Johnsons use the same alias, however. Some of the human Hans Brackhauses might even be using masking to fake the astral signature of a dragon to scare people into thinking that they're Lofwyr in disguise.
He's a dick, even by dragon standards. For comparison purposes, consider that his brother Almaise was considered kind of a dick even by dragon standards back in the Earthdawn days... and Lofwyr made him look like a chump.
His go-to spy and fixer during the artifact rush was Simon Williams, a British neo-anarchist punk who turned into a lizard man when the comet came by. Lofwyr tracked him down thinking that he might be a drake (he wasn't, but he might be a t'skrang from ED) and then gave him a job, despite him being mouthy to the point that most people would have been eaten. Williams likes to hang out at a Godzilla-themed bar called The Rubber Suit in Seattle, pretending to be part of the scenery to dick with people. He was in opposition with some elven assassin/fixer working for Lung for info on artifacts, and if you're running Artifacts Unbound, he might hire you to assense the Maltese Falcon.
Oh, and Lofwyr is gold in color. Fitting, no?
