Any Guild Wars Trilogy Trial?

I was just wondering if there was a Guild Wars Trilogy trial, as I'd like to try out an Assassin or Dervish but the trial I've found on the Guild Wars website, only allows you to try out the classes from the very first game.

If anybody knows of any such trial, or perhaps has some kind of trial "key" they wouldn't mind letting me have, it'd be much appreciated.

Thank you very much.

No, there is only the Prophecies trial. When you purchase Nightfall by itself, I believe it came with a buddy key to allow a friend to try out the campaign with you, but there has never been an official trial for Factions and Nightfall.

NOTE: Only the CE had the buddy key and it also had a trial key for Prophecies and Factions.

Well if anybody has a buddy key, I have a code which gives special ingame Aion type wings as an /emote, so I'd be willing to trade if anybody's interested
