Igula gradually understood why the Gray Fox Mage used the cumbersome yet insignificant mechanism of the "Truth Link."
Because they not only wanted future generations to 'know,' but needed them to 'believe.'
Knowing is far too easy, like knowing there are icebergs in the extreme north that feel like they're on fire, knowing there are mountain-like whales in the deep sea, knowing a girl's lips are soft, but if you haven't experienced it personally, you'll only be stuck at 'knowing,' and will soon forget.
People know many truths, yet often live poorly, because they do not genuinely believe. The most interesting aspect of history is its continuous repetition.
This point sufficiently proves the practicality of the "Truth Link"; it is no less effective than "Sanctuary" or the "Twin System": it allows the youth to grasp the societal truths that require decades of experience to comprehend without the need for undergoing hardships.
