Interdimensional, a starship trilogy

"Quick, evacuate our wounded and dead heroes", ordered queen Quintara standing on top of the biggest armadilla before flying down to where sky marshall Egara lay helpless. The queen guard along a sizeable delegation followed her. While other warriors carried on the attack. Slashing at the armoured vehicles all over with iron clad talons. 


"You will be fine old friend, we are taking you home", said queen Quintara soothing holding his hand. Marshall Egara had been keeping an eye on armadilla from which she had jumped down from it. He saw it throw it throw the air the winged warriors attacking it high into the air and begin to advance towards them. 


"Get out of here!", he cried out desperately. 


"What do ...", she began but never got to finish as a mechanical leg slammed savagely into the gathering tossing them into air. As they fell back on the ground sky marshall Egara was still holding queen Quintara's hand.
