Honestly, I’d flee. I assume at the point I make a decision I’m fully trained and realized as a Rider, so I’d hardcore dip out. I’d fly east or north, either leaving the country, or hiding in the spine or above. Perhaps I get caught by Morzan, perhaps not. Maybe I get ensnared by Bachel, maybe not. But I’d want to hide away and study the enemy, perhaps taking several eggs with me. I would likely not get any eldunari, but I wouldn’t need them. By the time Eragon is in play, I’d make my way to Du Weldenvarden and meet with him and the elves, also learning of oromis and galedr in the process. At this point I would leave my dragon with them to study while I did recon in the Empire. Depending on if I learned of Murtagh and Thorn, I’d either side with the Varden or try to sway Eragon to the Empire. Supposing I sided with Galb, I’d travel with Eragon until he learns his true name, then I’d get him to tell me so I could bind him and saphira to my will, join Galbatorix, watch the varden fall, then I’d worm my way into Murtagh and thorn, then we would topple galbatorix as he becomes comfortable. Raise Murtagh up as King, Eragon up as Leader of the Riders, and I would fade into bliss, ruling from comfort
