From Guild Wars 2 Wiki
- These lands are plagued by corruption and undeath. The plants I've scattered in the swamp below will help the land retaliate against this evil.
How will they do that?
- They're weapon-like plants that will grow and sustain in hostile environments. With them, we can push the Risen out of Murkvale.
What's the catch?
- The magical soil they grow in attracts Zhaitan's corruption. If you find the soil in the swamp, clear the corruption so the plant can regrow.

- Good luck with your work.
