Jujubreaker

"The crowbar is a pretty relevant object. This unassuming maroon tool makes it all the way to the bitter end of the story, smashing this thing and that. Its ability to "destroy a temporal artifact" seems like an arbitrary property for a Felt weapon to have at this point, but it fits more broadly into lore developed much later on. The egg timer is a juju. The crowbar is a juju breaker. Anything that qualifies as a juju, or has juju-like qualities, can be destroyed by this thing, making it an extremely powerful and consequential object that is also a juju itself. By my even saying the word "juju" here, two things are happening. One, the word "juju" now sounds kinda funny. And two, I'm getting ass-deep into cherub lore, which is DEFINITELY something I shouldn't be doing in such an early book."
