Thank you. Think all approaches are interesting and thank you for the link.
Question. Do you fight risking your life in the Forbidden Lands for an artifact and few golds ?
I wouldn't treat artifacts as rewards. Use artifacts to drive story or campaign. Many artifacts given in the GM guide tie either strongly or loosely with Raven's Purge. The artifact could be the hook that gets them involved (or doesn't if they choose to just get rid of this potentially troublesome thing or choose to seek out an interested party to buy it who themselves may be a hook.)
PCs in the Forbidden Lands are assumed to have the itch of adventure, curiosity, wanderlust. They go and do these things because they can't help themselves. They risk their lives because they're not content to just sit in their villages and grow old. They seek out legends for the sake of seeking out legends and rewards and fame are bonuses. Treasure is likely ephemeral and anything of lasting value draws the attention of potentially jealous competitors.
