Do the different Towers have different areas of specialisation?
Like, both of the Fourth Tower Masters (Essiahel, Mikel) are known for dabbling in forbidden magic and human experimentation.
The Third Tower Master (Karazan) seems to be their envoy, being sent to the council meeting to speak on their behalf during arc 4 and later being sent to the Palace to assist affairs in arc 5.
The Second Tower Master (Benedict) seems to deal with PR and outsiders within the Tower, having tea with guests and constantly calling out to the opposing side about how they'll be dealt with during the all-out brawl with Association during the late 4th arc.
The First Tower Master (Meredith) is of course their leader and head of the whole organisation, as evidenced by Meredith's orders and authority over the others; something which Karazan says will all be his going forward when he rebels against him.
