So you installed the aether mod and then your alignment got reset, or you installed the aether mod after your alignment got reset? Assuming its the installed it before, then it is most likely the problem. Since there are seperate player.dat files for your inventory and alignment, quests, etc, this explains why your inventory wasn't affected but your alignment was. As for the 15 alignment with the factions you mentioned, if you didn't kill anyone, then I would guess that your file got corrupted.
