Gejutel is Regis's grandfather and carries himself with a walking stick and monocle. As the current leader of the Landegre clan, he's notable for being the sole survivor who actually served under the previous Lord—a position that sets him apart from the other clan leaders, most of whom either went into eternal sleep alongside their old master or betrayed him outright.
He shares Regis's strong sense of honor and isn't shy about testing his grandson on it, particularly when it comes to the treatment and protection of humans. The guy has a reputation for being somewhat at odds with Frankenstein, which creates an ongoing tension between them.
What's interesting about Gejutel is that he was given a secret directive: guide the current Lord and help smooth things over during the transition when the previous Lord and his clan leaders fell into eternal sleep. It's basically a stabilizing role he's maintained through centuries of upheaval.
