You order the Army to go and punish the Fomorians for their crimes.
4*
The Army reports a victory, but the Fomorians were fearsome during the battle, especially their chainmail-covered, huge-axe-wielding Queen, not to mention several Fomorians coated in tatoos made with woad who caused the earth to open up under people to swallow them alive. The battle caused over thousand of casualties amongst the troops and a loss of two hundred mounts.
Nonetheless, the savages in the end fell before the might of your Army, which managed to slaughter each and every one of them.
821 AD, Midwinter
A seven feet tall, elderly man in white hooded robe, strange jewellery and raven-black beard demands an audience with you. People say that one of his eyes is blue and unmoving, other is green and that motes of light are swimming in that green one.
You allow the wizard into your throne room.
"I heard that this earthly domain requires of me services." His voice sounds raspy and gives you chills on your spine for some arcane reason. "Speak, you."
You explain the whole deal with dwarven tomb, their curse, and your problems with stillborns.
"You hath angered them, silly king, you should be actually praising the dwarves that a bodily curse is all that befell on you." He smirks at you, patting his beard. "Ah, but dwarven magic is black magic, and I do happen to know how to dispel black magics and curses of both gods and mortals alike. How shall you pay for me services, oh troubled liege? I shall say that I do not need your riches, because as you can see, I travel with naught but things I wear on meself."
