a trapdoor

Seen 1 time. Last seen ??.

the shovel strikes the ground, but instead of sliding through the ash or dully clanking on metal, the ground rumbles, a resounding hum echoing briefly before fading out. you dig out the surrounding area and reveal a square trapdoor, with a metal handle sticking up.
