This is Don, the sentry of guild Rapidscale. Putting on his favorite tie, he gets ready to head to the top floor of the guild and starting another day of watching out for guests.

The way this sentry system works is that Don is sat up in the ear tower of the guild, watching a camera he set up to see who enters and leaves. There's also a sensor system that alerts him when someone's entering or leaving. He looks at the cameras to log who comes and goes, keeping this information stored in a filing cabinet. It can get boring up there, so his guildmaster allowed him to bring books or things to entertain him as he works, but he still must be alert to log down and let guests inside.

It's a pretty basic drawing, but Don's a funny little guy. He's kind of a jokester, but he doesn't get annoying with it. Just another brilliant member in the technology driven guild!
