The Pyrrianaut

Lt. Edward Philips is a Pyrrianaut, one of the elite soldiers used by ColAdmin to guard their off-world colonies.

And he has a problem; well, two problems:

At 22 he's getting too old, and his mind too set in it's ways, for the neural link to his armour, and he's going to have to retire soon, and he's not sure what to do, but that's going to have to wait until he resolves the more immediate problem: a gigantic alien pseudo-dinosaur is about to fly into his colony, and he's going to have to stop it.
