Dragon's Rook

Jarl and Mirza Koenig have decided to take a vacation far from their responsibilities as guardians of Realm and the other known worlds. Before they go, they leave a proclamation putting Seren, their oldest son, in charge until their return from their secret hideaway. No sooner are they gone than a fairy lord returns from prospecting for gems in space, wounded by some creature that has left huge bites in his body. After he dies, Arthurian, the Sidhe King, demands something be done. The situation requires Seren to leave his commission in the U.S. Army and return to Realm. He and his younger brother Argen join with the dragons and other magical creatures to become the defenders of all the known worlds. Who are they fighting, and how do you fight a war in space?
