uh huh...QM...I wouldn't dream of God Modding anything in any situation and don't claim to know the answers, but I think them finding the location first off would make Silven go hmm ok someones coming by this region that no one ever comes by...either A. Kyn did her mission or B. She betrayed me.  At which point he'd activate the bobble he gave to her to check in on what she was doing.  If she was with other people nearing his home, he is A. Going to nuke the house with blight fire, B. Slit Anoria's throat if she is in a situation he can take advantage of and then hearth out or C. If he can, knock Anoria out and just leave with her or the back of his netherdrake.
