Hypotheses

-Based on the Vision of Truth , the psyker detection device , and the differences between Navigator and Psyker abilities, Quint has hypothesized that  Lady Tarquinius is intending to rip a large hole in the Immaterium using (perhaps several) witches.  

 -Quint has speculated that the Lady Navigator may herself be in possession of one or more Asterii Devices , specifically a Voiddelver and/or a Communior .
