A task for an Incubus, aided by your draconic blood.

"Minion, I have a task that will require both of your heritages to be used." You nod. "In the upper reaches of the human lands, there is an iron-rich valley. That one valley supplies nearly half of the iron used by the human armies. I want you to go there and corrupt the lords. Force them into submission, and get them to stop producing the iron. Without it, we will be much better placed to win when I bring the barrier down."

"Yes, lord. But you said both heritages, I only see how my incubus powers aid me here."

"In the valley they almost fetishise dragons. They think that the iron comes from the bones of dead dragons. I want you to take advantage of that obsession and your form, and use it to your advantage. Understood?"

"Yes, lord."

"Good. Then fly."

You adjust your clothes a bit (even if your powers form the basis of your seduction, you still want old-fashioned charm up your sleeve) and start the long walk back out of the armoury.

You stand in a courtyard of black bricks, set out on the very edge of the castle. You beat you wings, carrying yourself up to the wall surrounding the courtyard, and then glide off, heading towards the site. Oddly, you know exactly where to go, but he never told you... and why did you feel like you had no choice in calling him lord?

"Because you did not."

Well, that answers that. You fly on, over burnt forests and chasms filled with lava. Eventually, you near the barrier, and drop to the ground to cross...
