The Helvati did not record their history in written scrolls or books, the practice having not evolved yet due to a variety of reasons.
One was because their culture was relatively young, so their civilization had not advanced enough to require such meticulous record keeping. People still trusted each other enough to believe whatever they said without requiring any material proof.
This lack of complexity aside, the second reason for it was due to the fact that the place they lived in did not have easily available material to write on- such as papyrus or stone.
And this was perhaps an even greater handicap as evidenced by many examples from Earth.
It is hypothesized that the four great ancient civilizations of Earth- the Mesopotamians, the Egyptians, the Indus Valley, and the Chinese became great civilizations because they all had access to good writing surfaces.
