Description from itch.io:
In the Firebringer are two self-contained adventures around The Garden of the Spire Queen.
The Missing Historian is an investigative adventure around a missing scholar, Edmund Winterholme, who was personally tasked by the Spire Queen finding clues about a powerful weapon. It contains a chart with the characters relations between each other, a chart where to find clues and what actions take place while the players investigate the case.
The main adventure though is The Temple of the Blazing Sun. This adventure starts with the information gathered by the historian. The players travel to another hex and find the hidden entrance to the long forgotten temple. There they'll find a riddle regarding the Firebringer to get to the shrine in the middle of the temple and the old artefact. Inside the temple they are confronted with the long dead, but also a new inhabitant.
