You were a poor worker who died in his office, now you wake up as a baby, when you recover consciousness you see some signs and finally you recognize it, the burgundian cross.

So this is you, a man that reincarnated into the bastard son of the duke, Burgundy is a country were many changes happened in less than a century, the hundred years wars, the golden era and the Burgundians wars that split this raising country, ending the dreams of form a new Lotharingia, now knowing it's your turn, the hundred years wars events are changing from what historically happened, burgundy keeps involved, you certainly would be fighting the french, Charles the bold is still a kid, that man would led burgundy to it's fall, so you would try to be in the succession, educate charles to prevent his desire of order and strictness lead him to catastrophe or enjoy being a low noble, it's up to you, but what is certain, if the Burgundian state fall, you would need to look were to hide if you don't want to be another medieval corpse.

Your reincarnation have changed some events, accelerated one, slowed others, but they would still happening.
