Shady Nightshade

After the group escaped Cirflucas via a teleportation Circle in the White Palace, they ended up in Austium.   After telling their story to Markvart Blakfort, they were assigned to Sabrina Niryrr, also known as 'Nightshade'. She allegedly arrived from the Righteous Kingdom of Yi'riila to investigate the disappearance and probably faked death of their Primas.
