So Fireau is running after the last orc...<br/><br/>Now I'm not saying that there can't be half a dozen orcs who hide in the woods all day on the off chance that some magical girls invade and overpower the welcoming party, but my decision is informed by the following:<br/><br/>1) The terrain is open and clear enough to use the run action, meaning that visibility can't be too bad either, and Fireau can probably spot half a dozen orcs at a distance,<br/>2) The orcs obviously weren't expecting a magical girl attack, so if they're present at all, they're probably not hidden. Or, the retreating orc has to get their attention by yelling or some other signal, which will again let Fireau know the odds ahead of time,<br/>3) The chase won't last even a fifth of a mile. If there were reinforcements so close, they've probably heard the noises of combat already and would have moved up to support the welcoming party; the orc retreating probably means that there aren't any reinforcements close by.
