Lex tried to recall what he knew about bloodlines. Once, as Leo, he has asked John about the topic of bloodlines, and he had seen some random bits of information while casually browsing the portal.
Bloodlines in Beasts was an entirely different topic, for the Beasts' entire cultivation was based on their bloodline limits. But for other species, such as humans, it was not the same. The basic gist of it was that it was something that gave whoever had the bloodline access to special powers or abilities.
But the source of that power was a mystery to Lex, as well as how their limitations were defined, because the Inn workers truly had some broken bloodlines.
