[Knowledge] Letusa Expedition's Rules

The initial Letusa Expedition was composed of sorceresses
who were either secretly selected by Ahon Kirus
to investigate the truth behind the Three Days of Darkness that struck Ulukita,
or supporters of investigating the Tungrad School to uncover their Black Spirit's Rage experiments.
These days, however, the expedition consists mostly of
scholars and mercenaries supplied by the Crow Merchant Guild.
The expedition sets out in parties to investigate for four days at a time.
Upon their return, the members hold a meeting
to exchange any information they have gathered,
then they plan for the next trip based on their shared findings.
The rules for an exploration party are simple.

Since the protectors of the Tungrad Ruins
bear the all-too-familiar energies of the Black Spirit,
each party must contain at least one member
from the search, combat, and ruins exploration teams.
