Quest 54

Walkthrough

 * Talk to Agapei in the back of a private house entering from C-7 in Glen Castle Town and accept the quest. He speaks of overcoming anxiety and doubt.
 * Head to Nagua Caves, which is west of Langau Mountains. If you have not been here before, you can reach it by venturing to Lion's Gate from Glen East, and then taking the north exit.
 * In Nagua Caves, there will be another unlit bonfire. Interacting with it will trigger a cutscene. Watch it to the end.
 * When you come to, watch the cutscene again, but this time escape a terrible fate by selecting the "No." option.
 * Return to Glen Castle Town and talk to Agapei to clear the quest

Completed Summary - I escaped the consequences of becoming a madman by going to the Caves of Nagua in the Langao Mountains as Agapei, a resident of Glen Castle Town, had told me to do. Agapei gave me a gift to celebrate.
