Any National Heroes in Faerun?

[Aikamun]

Greetings all,

I have played around 150 turns total (three games) on the large Faerun map and have seen zero national heroes. The specific map is the large Faerun with special starting locations. Some settings which may be the reason: Order Three, Misfortune One, Common Random Events, Special Events Enabled, One Starting Location. Have had two Lore Masters and one group of flagellants arrive though.

Is it just my bad luck or do I have it set-up incorrectly to allow for the arrival of national heroes?

Thanks for your time,
Aikamun
