You have done well with your duties. Once you have made your final shipment, you may inform the maharaja that our debt is settled.
The final shipment of dryad poles will be enough to complete the project. Cessation of iron shipments caused the project to slow, so focus on finishing up your operation in the Fey Wood.
Consider a final strike against the elves. They have something I want. I am told they have a map in their library locating the Tomb of Bonebreaker. Within the tomb is rumored to be a spellbook with a map to Aparnisi. It may be the foothold I need to locate the first part of the rod.
Finally, although your debt is paid, consider another task for me. We have suffered an incursion of undead from a valley to your south, much as you describe against Tara. I believe it is from the same source as Bloody Erik and the hill army that has vexed you and Aillyn.
I wish to understand who is responsible for this, and why they both attack and protect the Tarans. This incursion has taxed our resources. There are many fine young ladies available to you if you complete this task.
