What's a "Guild?"

A small black bird pokemon stood at the Grassveil Guild entrance, bewildered by its grandeur. He wasn't completely sure he'd reached the place that the pokes from the pond had mentioned, but this structure fit their description, even if vaguely. He'd never really seen a building so artful. Of course, there were plenty of great things to see in Grassveil town, but along the way to the guild he was too busy bobbing between the many strangers frolicking about. At last, after an episode of scurrying through crowds and getting lost, he found it. Nighttime came swiftly and the city was more peaceful. Even now, when there were only a few pokemon roaming around, he was unable to enter because of a petty fear of being swept into an uncomfortable situation. He tried and tried to muster up enough courage to walk inside, but had so many doubts and worries that he was immobilized. And so he stood out in the brisk wind on a lonely night.
