Nightfall Character to the Crystal Desert

I was just curious on if a Nightfall Character could travel or work to get to the Crystal Desert in the Prophecies Campaign. Thanks in advance.

Yes you could, infact there is an NPC in The Desolation that could instantly teleport you there.

your question isnt very clear but fo both cases :

1 - there's a teleporter in crystal overlook in nighfall allowing caracters who already been in tyria crystal desert to teleport there.

2- any nighfall caracter can reach tyrian desert simply by doing the sanctum cay mission.
