I cannot begin to comprehend why the naga would drain the water out of their own habitat. What I do understand is a need to put a stop to their operations.
These seeds carry with them the rage of the earth. Take them to the steam pumps operated by the naga and use them on their controls.
The vines that grow from the seeds will be as thick as your arm and as strong as iron. Go, [player]. Restore the balance that the naga have upset.
