The Reader Pathway represents the search for knowledge. In contrast to Hermit Pathway and Paragon Pathway, this pathway includes both scientific and mysticism knowledge. Beyonders of this pathway have a good memory and the ability to imitate others' powers by analysis. They are also skilled in ritual magic.
At High-Sequences, they can see the future, directly observe, analyze and use the fundamental laws of reality, and "read" all information about a person.
The Tarot card for the Tower actually represents disaster. This was selected by the author because in Lord of Mysteries, knowledge is also dangerous. Knowing high-level knowledge without sufficient protection could lead to corruption from various sources.
What's weird is that this is potentially one of the best pathways with it's sequence 6 Polymath being able to analyse all kinds of abilities and create their own spells with what they understand. And they can basically know everything before it happens and have the ability to make the best decisions.
Its actually quite neglected by author.

And the slander...
I think the old final ritual involved constructing a giant white tower, filling it with books containing all of one's (as a semi-omniscient being) knowledge and then swallowing it. I wonder why it was changed?

Yeah that author is crazy.
