Here's a test. Anyone know of/remember Si Ju Jarugi? He was a noble of Drachenwald who assassinated Achilles, Dictator of Tara, earning what was, at the time, the largest bounty ever collected.
Gauihu Olik and the role he played in Abington's death is forever immortalised through realm histories and newspaper articles. The wiki is the one sure fire way you can carve out your place in BM history, heh.
As it happens, I remember Si ju Jarungi. But bounties aren't a big deal. That's just an infiltrator's blood-money, not really infamous or evil (especially since infils generally prefer NOT to be noticed). The real infamous ones are villains like Delvin, Aldo, or Handkor; or Doc, for example.
The path to fame is indeed the Wiki: or, the realm. So, for example, few people remember individual Avamarians. But Avamar itself remains part of the game's "collective memory." Or the zillion incarnations of Tuchanon (which, by the way, if/when I succeed in forming a secession, it will almost certainly be called Tuchanon, even though I never played in any of the earlier Tuchanon incarnations). Or Sirion and Doc, for example. Our Sordnaz and BoM. Or, heck, Irombrozia (though we were kind of a backwater, admittedly).
Or consider Mathurin Hossenfeffer: a well-run religion is also a path to lasting fame.
