In the Ruins of Empire book it shows the Regency Generated for several
domains. However, as an example.. Marlae Roesone (who has NO vassals to
collect RP from) collects like 30RP each domain turn but her Bloodline score
is lower than that. I believe they may have mistakenly used the domains power
for these numbers. While the actual regency collected would be that of the
Bloodline or Domain Power.. whichever is Lowest. Just thought I'd point that
out to those who intend to use those numbers
