Necromancer Vhar'gor's Ghost Dragon

"'Vhar'gor Wyrmcrutcher has his very own ghost dragons too. They seem to be more stronger than any flying units available to ourselves due to its invisibility, an ability to damage our morale, and be bulletproof. Oh, and they even got a good speed, strong defenses and a heavy melee attack too."

--Su Ji-Hoon, The Ghost Dragon

The Necromancer Vhar'gor 's Ghost Dragons are undead dragons served for Vhar'gor Wyrmcrutcher - theNecromancer of his own Necropolis and his own Undead army that they are new undead version of H5 Ghost Dragons.

They are the skeletal remains of deceased dragons who want to be revived and have ghost form as become the ghost dragons by Vhar'gor Wyrmcrutcher. Maybe they were stronger than any flying units due to invisible,destroy enemy morale and bulletproof skills that they have good speeds with high defensive and heavy melee attack.
