WTF is Filoni smoking lads.
From the reliable MSW.

Thrawn and Ezra get lost in a new region of space. (We all assumed that)
The Nightsisters and other force users originate from here. He doesn't say it, but I assume he means the Unknown Regions which in legends is hinted to the origins of many force cultures. We already know the Jedi are from there originally. So that's not too surprising.
Lars Mikkelsen is Thrawn
''Can you imagine if Thrawn returned with the Katana Fleet full of undead soldiers from this new place? That would be nuts and give new meaning to the name Skeleton Crew.''
Interesting figs eventually, I suppose.
Its quite bizarre. I honestly think Filoni has gone a bit insane.
However there's an undead army of Nightsisters and undead warriors possibly under Thrawn's command like the Night King in GOT
