Where can I get trial keys?

can anyone tell me where I can get prophecies or factions trial keys for my friends?

The Preorder package for Factions contained a Trail of Guild Wars Ch1.

Factions, the retail version, comes with a trail key for all of NCsoft's other online games (Lineage II, Auto Assault, City of Heros/Villains).

There isnt (I dont beleive) a trail key for Factions itself.

yea but anywhere I could get a trial key now? for guild wars, not anything else >.>

Not unless you have a preorder kit, no, there is nowhere. Oh sorry actually you can get a 10 hour one with certain graphics cards, but I don't think you wanna buy a graphics card just for a free trial...
