Chronicle

The agents returned to discuss the cases and the book with Mallory, and to pick up supplies for dealing with petrification.
- 09e01
The SPI’s headquarters which the party discovered in the crystalline flux realm while riding the Yachtopus.
- 10e05
The agents teleported into HQ to find it corrupted: an undead branch crying out for water, an evil, root-shedding desk in Mallory’s old office, and a bulging wall of elemental earth over the hole in Cassandra’s lab. Beyond the earthen barrier, on a hilltop, waited a nightmare tree, a hezrou demon, and a chasme demon.
- 12e01
Burglarized: the agents returned to find Cal’s sword stolen, the crystalline Flux rift repaired with karach, and a mysterious monkey statue in the sword’s place. They secured HQ by changing its teleportation sigil sequence.
- 14e00
The agents told Mallory it was more or less repaired.
- 16e01
The trap door in the basement, which only Bec could open with the Celestial Hand, led past an invisible forcefield that Ozborn, Cassandra and the agents could pass through but Mallory could not, down to a realm resembling the Afterworld. Cassandra, who had found the building for the SPI, was sure it was safe.
- 16e09
Callie’s word of recall brought the agents back to her shrine at HQ. Bec listened at the basement trap door, hearing only a spiritual whooshing, and closed it; it vanished without a seam.
