“There,” he said, “beyond the top of the arrowhead, is where we were going when the Gerns stopped us a hundred and twenty years ago and left us to die on Ragnarok. It’s so far that Athena’s sun can’t be seen from here, so far that it will be another hundred and fifteen years before our first signal gets there. Why is it, then, that you and all the other groups of children have to learn such things as history, physics, the Gern language, and the way to fire a Gern blaster?”

The hand of every child went up. West selected eight-year-old Clifton Humbolt. “Tell us, Clifton,” he said.

“Because,” Clifton answered, “a Gern cruiser might pass by a few light-years out at any time and pick up our signals. So we have to know all we can about them and how to fight them because there aren’t very many of us yet.”

“The Gerns will come to kill us,” little Marie Chiara said, her dark eyes large and earnest. “They’ll come to kill us and to make slaves out of the ones they don’t kill, like they did with the others a long time ago. They’re awful mean and awful smart and we have to be smarter than they are.”

Howard looked again at the Athena constellation, thinking, I hope they come just as soon as I’m old enough to fight them, or even tonight.⁠ ⁠…

“Teacher,” he asked, “how would a Gern cruiser look if it came tonight? Would it come from the Athena arrowhead?”

“It probably would,” West answered. “You would see its rocket blast, like a bright trail of fire⁠—”

A bright trail of fire burst suddenly into being, coming from the constellation of Athena and lighting up the woods and hills and their startled faces as it arced down toward them.
