(SPOILERS FOR 5.2!) My theories after finishing the Audiologue

Right into the meat:

The Fatigues (except Wernon) were/are Pentex Boardmembers

Amanda is related to Wayda, either being a descendant or just from her community

THE FLY IS WYRM INFLUENCE, thats why the flies came when Kitten and Amanda had their depressive fits, and why it was the last thing heard after the cast left to meet the Coalition. In fact, i believe the Arcanum may have stored a fetish or even Totem of a fly spirit, either knowing or unknowing.
