A leaflet is placed in the usual spot on the noticeboard.
Dear Botanists,
Stormwind calls for aid! Something very suspicious has apparently sprouted somewhere around the local cementery. From the rumours floating around, we might need to flex more than just our green-thumbs. Bring something that can be used as a weapon and let’s get weedwhacking!
Quest Objective: Make your way to the Greenhouse at the Magus Commerce Exchange during twilight on the next Night of the Moon (16th of March at 20:00 server time). For extra immersion, feel free to bring an Inky Black Potion if you have any lying around!
The Botany Band is a roleplay guild with focus on adventurous study of plantlife. We welcome every friendly adventurer with a green thumb! 
Hopefully we’ll get it some other time!
