Lenny Tales King of...
Lenny discovered early on that they were two kinds of True names. There was the 'True name' and then they was the 'False-true name'.
The true name came about when one's own bloodline acknowledged the efforts of its person and blessed them with an escape of more strength or power.
This sudden increase usually made the individual more formidable. Lenny had met a few that had the True name and had proven to be very terrifying fighters.
Of course that was a long time ago. According to the books that Lenny had read from the Satan system, there seemed to be more benefits attached to this, but of course, this only occurred with the growth of one's power.
Lenny himself had no True name. However, what he had were titles. With the gift of titles or a Truename, one had the privilege of blessing another with what was called a False-true name.
