Hi all,
Currently, you have 3 minor keys associated with Norah Stone/Sister Shadow.
Those are #1056 (1st cameo), #1057 (1st app), #1060 (1st app Norah Stone as Sister Shadow).
However, all those identities are aliases of Janan Al Ghul who first appeared in Batman/Superman : The Authority Special #1.
So, i believe the correct approach would be to upgrade Batman/Superman : The Authority Special #1 to a minor key (1st app Janan Al Ghul), downgrade #1056, #1057 to non-keys, and change #1060 as 1st app. Sister Shadow (Janan Al Ghul), and to be honest, im not sure that the latter is really a minor key as well.
I know, i was confused too
Thanks a lot,
