Agreed. I undestood it completely. Thanks a lot! I totally agree with the Elven Protector being kind of like a "boss monster" relationship. The Suspicious archer druid PC who had a somewhat little-sister relationship managed to break through to rank 10 early in Part 5, which flabbergasted some of the other characters who were much further back.
Based on your review, you'll be happy to know that once I finish some of my other freelancing commitments, I am planning to work to finish some LG releases for more character options for relationship NPCs! I actually have dozens of them for my own GMing of a Far Eastern Adventure Path, in fragmented sentences and notes "for me" that basically just need me to translate from Mark notes to English. That said, such a translation takes a lot of time.
