Question regarding GW Ch.1 trial keys

Well, I was wondering how it works.

If you already own factions, and wanted to try out Proph first, could you just use the trial key to buy some proph-only skills, proph-only items, and still have them in the future after the trial ends?

Or will they just suddenly disappear? eg Waking up one morning to find all your proph elite skills gone.

I don't have a trial key, but just wondering if this could happen.

How do u get trial keys?

Trial keys come with the game. In the box, along with your standard key, there was/is a 14 day/10 hour trial key to give to a friend so they can try the game and you can sneakily get them hooked so they come to you begging for their next fix...erm...I mean so they can see just how wonderous the game really is and subsiquently prance to their nearest wal-mart/target/eb games/whatever to buy their very own copy from the magical GW fairy...no wait, that's not right either...

anyway, there's a trial key in the game box to give to a friend...I've been trying to find someone on here who'll get me addicted...um...who will give me the trial key they have so I can see if I like the game... If I like it, I'll go buy it and then offer My trial key (that I'd be getting in the box) on here for someone else...
