Ask an expert if you aren't 100% totally sure on something! Try a council member, one of us will always get back to you! Between the group of us, we know all there is to know about Pern, so go on an ask! We don't bite... much.
Be logical. This means we don't want to see any 100 metre long bronzes, people with wings, or anything else along those lines. No Klingons, mysteriously magical or religious people (magic and religion to not exist in Pernese society), or landings of rescue teams.
Courtesy gets you far. Stupid and nagging as it may seem, this one always works! A few "please"s and "thank-you"s will work wonders in getting you what you want.
Don't forget to check out the list of Valihian Dos and Don'ts, either, it can help too!
