Sorry, but I've got one more entry into the voting options. I feel sorry for Old Jon and hold Luthor in contempt, so I would prefer to help the former and do away with the latter. Lord Elwood can go right on hating magic, since it keeps the Fey from coming in and setting up another pact without more effort on our part. When we seize control of the Reach, it won't matter one iota whether Elwood hates magic or not.
[X] Plan Grabbing Everything Of Value And Cleaning Up Loose Ends
-[X] Attempt to recruit Old Jon, offering him a stipend and to Resurrect his family in return for letting the Scholarium study his condition. When the research is finished, he and whichever among his family chose to return to life will be relocated elsewhere in the Imperium, to a locale where they will not need to resort to poaching to survive.
-[X] After collecting what samples we need for Resurrection purposes, use one or more Miracle spells to scour all remnants of Luthor, Old Jon, and his family from the forest, removing the abandoned home, dried blood, their graves, etc., so that there will be little to no evidence of what really happened.
-[X] Kill Lord Luthor to tie up that loose end. He was a miserable sack of shit in life, but perhaps his body, once fed to the Flesh Forge to gain the Wereboar Template and hopefully more knowledge about lycanthropy in general, will be of use in the future.
-[X] Allow Lord Elwood to hold on to his prejudice against magic and his mother to keep her secrets. For now.
