Dragon of Blackfire

I'm writing a book called Dragon of Blackfire Mountain. A prince named Merth finds the enemy in the North was coming to take over Elenrethiel(city in the province of Acern). His father dies and Merth is to decide to travel to Itir Ereth to destroy Oakberin, lord of the North. The ally city of Mieldor is to come and live in Elenrethiel and Aronel(king of Mieldor) is to rule. Merth faces the Argul(the treacherous men/elf of Erein forest) and now he is with the elves. An assassination is about to take place in the Elves domain.
