What the achievement asks
The public achievement description says to meet the tree with Perr. An older guide places the setup after Chapter II: speak with Perr around the carrot farm, then reach the floating-island tree.
Why current players may be confused
The relevant character may be named Fel in newer versions and can appear at the upper-left of the carrot fields. This conflicts with the achievement wording, so check both names instead of assuming your quest is broken.
- Check the upper-left area of the carrot fields
- Look for Perr or Fel depending on the displayed version
- Complete the conversation before pursuing the floating-island tree
Missable-state warning
Later-chapter availability can vary by version. Make a backup before advancing past the relevant chapter, and complete the conversation as soon as the character appears.
