One of the Deltans, in an excess of zeal, hauled off and threw his pointy stick at the fleeing gorilloids. In one of those moments that change the universe forever, the stick flew a trajectory that would make an Olympic decathlete proud and buried itself in the back of the neck of one of the targets. The animal fell over like it had been pole-axed, and skidded face-down to a full stop. The other two didn’t even miss a step.
