Hi. I'm Ollerus. I found interesting stuff while re-reading OT volume 4.

From Toaru Majutsu no Index Light Novel Volume 04 Afterword:

The readers who read this volume should have discovered that the main topic is 'summoning spells'. Actually, there are all sorts of 'summoning spells'. There are those necromancers that can spirit dead souls into their bodies to those talismans that can input the power of Mercury. There are all sorts of summoning methods.

Those necromancers that can spirit dead souls into their bodies seems like foreshadowing of Esther Rosenthal.

Those talismans that can input the power of Mercury seems like foreshadowing of Lady of the Masquerade Ball. She can summon Taphthartharath, the Planetary Spirit of Mercury.
