Kempf has been changed to join as Rilke when Kempf and Ilios join at the same time in Chapter 16A.
Until now, Ilios and Kempf basically did not join at the same time and only joined at the same time on a particular route. Because of this, the two of them had the problem of sharing the number of wins and losses. This change is a measure to separate the numbers. In that case, Xavier does not join, so Rilke is Xavier's alternative.
There is no need to change the name or look, but the context was there and I let it follow. There is no difference in performance.
As for the conversation, the only thing I have changed so far is when he joins. He now takes off his mask when he talks to Amalda and Reinhardt, but it might be more interesting to build the wearing of the mask into the story.
What is Rilke?
I don't think you know about Rilke unless you have modified FE5, so it may need an explanation. In the original, there is an unused unit named Rilke, which has the same face as Kempf. It is unclear what the purpose of this unused data was in the original because no one has a clue. Kempf calling himself Rilke is a reference to this unused data.
