Sun-Key of Caldus
Ancient Key · Major
What It Is
The Sun-Key of Caldus is a brass key marked with Seraphine-era solar geometry. Caldus recovered and preserved it during his final investigation, and the party takes it from the murder scene beneath the Old Royal Observatory. The key is not a universal magical lockpick; it is specifically recognized by sealed infrastructure connected to Seraphine’s hidden routes and the sanctuary beneath Lake Auriel.
History & Provenance
Recovered from Brother Caldus beside the breached solar vault
Role in the Story
The Sun-Key converts Caldus's unfinished research into physical access. It allows the party to move from documentary clues into spaces the conspiracy cannot erase simply by burning records. Its repeated compatibility with sealed solar infrastructure also helps establish that the observatory, Lake Auriel sanctuary, and other Seraphine-linked sites belong to a connected historical system.
Known Properties
Opens specific Seraphine-era solar locks and sealed passages; carries recognizable solar markings; functions without requiring the royal seal; does not establish access to unrelated ancient mechanisms.
