Sophies new side story in Crestoria gave us some really nice worldbuilding
Sophie is still Protos Heis, with the primary difference being that she was made in this universe to go after Kasque (the storys villain) and now she has a weird side effect that monsters are drawn to her and will go and kill everyone around her if she dares stay anywhere.
Julius for sure wants her dead now. Idk why he didnt just kill Asbel, Ange and Sophie. They seemed to think they had absolutely no way of handling him, and it looked like he just gave up, unless I missed something. Its not like hes not interested in continuing the pursuit, Asbel had Sophie change her name specifically because Julius was going to come back with more muscle.
