Description

Riiiing, riiing — every missed call from the Hollows will be answered by Krampus' top-tier customer service!
That playful line hardly captures the weight of old obsessions, grudges, and regrets carried through those calls. But in truth, it's the most earnest vow of one prepared to bear that burden.

"Everyone else enters the Hollow armed to the teeth. Why am I the one carrying a bunch of phones?" —Dialyn, venting to her boss about her assigned gear.
