The Shadowrealm was called Xibalba.
Even among the countless ancient Shadowrealms, it was old, and unlike so many of the others, which were beautiful and complex, it was crudely simple.
Xibalba was a single cave, impossibly vast, unimaginably high, speckled with slowly bubbling pits of black-crusted lava. Occasionally, one of these would rupture, spitting thick globules of liquid rock high into the air, sending shadows dancing red and black on the walls. The air stank of sulfur, and the only illumination came from a gelatinous yellow-white fungus that coated the walls and the massive stalactites hanging from the distant and barely visible ceiling.
Every Shadowrealm opened onto at least one other realm. Some connected with two. Xibalba was unique: it touched nine other Shadowrealms and was sometimes referred to as the Crossroads. Arranged at regular intervals around the cave were nine separate openings in the walls. The entrances to each of the cave mouths were carved and etched with crude and blocky glyphs, and although the sticky glowing fungus covered most of the dark walls, none of it even came close to any of the symbols. They were the gates to the Shadowrealms.
Usually, nothing moved in Xibalba except the bubbling lava, but now a steady stream of messengers was flitting and scrabbling from one cave mouth to the other. Some were leathery and resembled bats, others were furred and looked like rats, but they were neither, and none were truly alive. They had been created for one purpose: to carry a message from the heart of the Dark Elders’ Shadowrealm out into every connected world. Once the messengers’ task was complete, they would melt back into mud, sticks and scraps of hair and skin.
The messengers were carrying news of Dr. John Dee’s death sentence.
And none of those who heard it-Elder, Next Generation or immortal human-were surprised. There was only one price for failure, and Dr. John Dee had failed spectacularly.
