There is actually more evidence, not mentioned by the user, which supports this theory. For example, in Timekeeper’s lore, a fallen kingdom is mentioned. Thus, they mention something about restoring a kingdom. Perhaps… just maybe, this is player’s kingdom.
Moreover, looking carefully at the characters in both Kingdom and Ovenbreak, more connections can be seen, such as Sugar Swan is present in both games. She is corrupted in the Tainted Forest, and is purified in the end. In Trip to Paradise, Sugar Swan states that she is late, which can be explained by the incident in Kingdom. Therefore, Ovenbreak takes place shortly after Kingdom.
Now, about the inconsistencies… the fall of player’s kingdom is too traumatic for Cream Puff, causing memory loss and personality shift; Gingerbrave is taken back to the oven where he breaks out again, indicating that he escapes it twice.
If this is the case, then there is a perfectly reasonable reason as to why Roguefort and Walnut isn’t in Kingdom. Perhaps the Blue Cheese Manor is still in its full glory, so Roguefort doesn’t have a reason to turn to thieving. As for Walnut, she is born, but she isn’t old enough to be a detective yet.
Couldn’t decide if princess or wildberry got the the soul jam so I just drew them both….
But this is an au where the ancients decide to pass down their soul jams for whatever moral reason idk I’m not making a story I just wanted to draw the idea
