One of the things that I occasionally get curious about is my own lineage. The question tends to come up when I stumble across something that supposely only those with "real" lineages are supposed to be exposed to---something that I already know despite my less-than-golden lineage.
The last time this happened, I was leafing though Mather's Last Secret. And I was like, "Oh, that is where that traces to...gee, I wonder where Hathor Temple got the information from."
This curiosity is always momentary. Within an hour, I had moved onto bigger and better concerns. Quite honestly, my lineage is not important to me.
I think that this is a reaction to dealing with some people who claimed super-great lineages, but were in the running for most abusive occult leader ever. If lineage means that one gets to be an a**-hat, then I would prefer to lineage-less. It was also the same attitude that Hathor Temple had---which is a whole another story for another day.
