On X-files portal:

• Lost objects: archaeological remains, forgotten secrets, missing heroes...
• The Cave: Informations close to the spoil that the player is not "supposed" to be known in his role play.
• Behind the scenes of the Encyclopatys: tips, tricks, explanations... very useful for the Encyclopatys or for the game, but difficult to categorize, because it could be a mix between technique, gameplay, RP...
