Kurt. He was cold to the group when you first met him. Booted you right the hell out of the base. He was using Fourier's research to attempt to extract eleth from the Valkines Cryas. Carelessly ignoring the dangers the research poses under the perception that Fendel is doomed one way or the other. But when you defeat him, the machine begins to act violently. In order to stop it, Kurt slams his spear into one of the power lines to force it to shut down. Gave his own life to that his entire nation could continue to live in hopes that things will get better. After all, he was only doing what he did for the good of Fendel, so his countrymen didn't have to live the way they were. So they could all have a better life. Kurt was a goddamn hero. Also also, going farther into the cave you'll see Lorelia's tombstone with Kurt's locket on it. Kurt loved Lorelia deep down, but he kept his feelings to himself out of respect for Malik.
That man was a goddamn bro to the very end.
