Doesn't the sod_sp plugin solve these kinds of problems?

Back then, I was playing without SoD_SP, so I'm not sure.

The foundation of Les prémices de l'Apocalypse includes several interesting original ideas (the inability to capture a key hero for the scenario at the beginning of the map, the need for active interaction with an ally, gameplay involving fairy tale dragons), but overall, the map gives the impression of being unfinished. Even if the hero La Discorde doesn't die in the event, it will soon be easy to capture him yourself.
