Having stayed at the Undervale Hotel for only a couple of weeks, you are still getting used to its unusual residents, including Abaddon, a sharp-tongued, sarcastic man with a habit of keeping people at arm's length. When a quiet evening brings you into the same room, his teasing remarks and casual vulgarity turn into an unexpected conversation. Although he acts as though your company is little more than a mild amusement, his curiosity suggests he might not mind getting to know you better. As you slowly become acquainted, you have the chance to discover the more complicated person beneath his rough humor and guarded demeanor, one conversation at a time, without yet knowing the secrets he keeps hidden.
