Interdimensional, a starship trilogy

Captain Maguire stood at the mouth of the cave watching the battle in the sky above as the Sandawana fired and captain laser beams in a brilliant flashs of light. He had never realised how truly spectacular the sight of a starship engaged in battle was. The Sandawana brought in the added dimension of missiles with the projectiles being fired from several of the starship'sgun decks. Their rapid discharge added to the extra-ordinary sight, that was at once beautiful and terrible in its destructive power. 


As the Sandawana hovered overhead, spitting a fierce barrage of lasers and missiles. It wreaked havoc among the attacking ships which were also firing fiercely. 


Lasers flew angrily in the space separating the Sandawana from starships of through the chaldarian order. 


Battle was joined as the chaldarians attempted to blast the Sandawana out of their way past the Sandawana and proceed to attack the mountain.
