Interdimensional, a starship trilogy

A random Drachalian missile struck close to captain Maguire threw him against a landing pod, knocking the air out . Recovering his breath he tried to hold on onto the tendril coiled around the landing pod for support and it gave way falling to ground, in an untidy heap, cut at the roots by the fierce barrage of falling shells. 


Captain Maguire ran to the other landing pods tagging at the tendrils around them and to his delight saw that while sime had been blown clean off others were only loosely holding onto the landing pods.
