- Talk to Horticulturist Hinon and find the whereabouts of the mehkuunah plant.
- Bring back a sample of the mehkuunah plant to Librarian Kahnu for analysis.
- See Librarian Kahnu for your reward.
- "Oh, ahai there. You caught me in the middle of my research. I made a recent discovery about a rather hardy desert flower that has far-reaching medicinal benefits. I can extract matter from its buds to treat night blindness, appetite loss, and depression with only mild hallucinogenic side effects. My problem? I'm having difficulty procuring more samples.
- I hear the Garden of Seborhin has a number of these rare mehkuunah plants. Speak to Horticulturist Hinon and see if you can find me more specimens. I'll pay you for your time."
- Accept: "A little fresh air and exercise will so me good. I'll get your plant, Kahnu."
- Reject: "I'm allergic to the mehkuunah. Break out in horrible hives, you see..."
Intermediate Dialogue (Horticulturist Hinon)
- "That old herbalist Kahnu needs a sample from the mehkuunah plant? Does he [sic] have any idea how toxic that stuff is? Well, all in the name of science, I suppose. Bear in mind the scent the plant gives off attracts cobalt beasts like you wouldn't believe! Check to the southern area of the gardens, but keep your guard up. And do yourself a favor and don't eat the plant unless you like the sting of fire in your belly."
- "Excellent! You found it! What's this... dried red substance on the leaves? Nevermind. Forget I asked. Hand it over and I can get on with my research.
- I've already gotten several solicitations from some interesting merchants about mass producing my medicine. They tell me it'll be a popular study aid at the university.... Oh, before I forget, here's your reward."
Take Tahlkora with you and take the western exit out of Tihark Orchard. The entrance to the explorable area of Garden of Seborhin is right outside; two steps and you're there. Talk with Seborhin Protector Zuor and he'll let you in.
- Once you take Primary Quest: Attack at the Kodash, you will not be able to get/work on this quest until you complete the Nightfall storyline (namely successfully complete the Abaddon's Gate mission). Abandoning the quest will not help. Completion of the Grand Court of Sebelkeh mission has the same effect.
- Interestingly, Horticulturist Hinon refers to Kahnu as "he", though Kahnu is obviously a woman.
