Illegal trading
Jagex has explicitly banned two types of trading: selling and buying RuneScape accounts, and trading RuneScape items and services for things outside of RuneScape, such as real world money or benefits in other online games. Despite the fact that Jagex will instantly ban anyone violating these rules, there is an active market for these illegal trades. On any given day one can find hundreds of RuneScape accounts being sold on eBay (however many of the bids are false). A very profitable website, buyrunescape.com, sells Runescape items for very low prices. Yet, Jagex has not taken any action against these pirate sites.
There are also entire websites springing up now, offering "professionally gained" items in exchange for cash. Items like the dragon chain body are on sale for $500 or more - The market is huge, but Jagex has insisted it won't allow it. (Particular reference to Sony, who decided to cash in on the trading of EverQuest items by opening up a legal trading ground)
The Fremennik Trials is an extremely long and difficult quest and should be considered by only those who call themselves "experienced" in the game. To begin, you need to trek up to Rellekka and talk to the Chieftain in pub. He will tell you that you need to get seven votes from seven of the twelve council members. Walk around the town and talk to random people until you find a council member. Do what they ask to receive their vote. Once you have seven votes, congratulations! You are now a Fremennik!
Gertrude's Cat
To start the Gertrude's cat quest, talk to Gertrude just outside of Varrock. After starting the quest, it is By the time of his death, the monarchy was all but abolished. Now the Kings in Keldagrim are but a distant memory... with only the statue of King Alvis to remind the people of the old days. The dark days.
So begins the Rise of the Red Axe, the new multipart storyline centered around the dwarves and their capital of Keldagrim. The first quest, The Giant Dwarf, introduces the city and the powerful business Consortium that rules the dwarven realm. Discover weird going-ons, narrowly escape from falling chunks of rock, ride around in minecarts and... make sure you don't bump into the wrong person on the way to the city!
