The herbs of the Barrens are not quite like herbs in other lands.  Their properties are mostly the same, but the oasis water here alters the plants; they are just slightly different.$B$BI want to study those differences... to see if they're exploitable!$B$BIf you are skilled in herbalism, then gather root samples off the herbs you find in the Barrens.  Bring back these samples so that I may compare them with herbs from other regions.
