[1.2.230] Black Magician rears his head

Im not sure if thats serious, a rule of thumb with every video game or anime is that theres always another major bad guy after the current one dies.

Then the rule of thumb gets broken a lot then. I've seen plenty of shows and games that have ended on a mark where there's nothing new for a next season. Take Fire Emblem for example. There's probably 6 different storylines in all of the 11+ games they have. When the world apparently changes, there's apparently nothing of the old world that exists. Also, the "Fire Emblem" keeps changing every time, and there's nothing suggesting that each of the "Fire Emblems" are connected in any way whatsoever.
