Moving From Factions To Nightfall?

I have a character lvl 11 in factions. I would like to move it from factions to prophecies and nightfall. what is the location in factions to move the character to prophecies or where is the quest to do that? what would be a reasonable lvl to do that quest?

I know there is the quest in lions arch to get to nightfall but what is the best lvl to tackle that?

If you have both Nightfall and prophecies.

Go to Kaining Center.
Go near to bejunkian pear you will see two npcs (soldier uniforms)
with questions aboth their head.

Both of them carry different quests.
1 is to get to nightfall, 1 is to get to Lions arch.

thanks

how difficult are the two quests to nightfall and prophecies? what lvl should the character be to do those quests?

thx

To Prophecies, its very simple, just takes a couple of mouse clicks. To Nightfall, however, involves clearing out Kaineng of a couple patrols of high lvl mobs. Best to equip a full hench team before starting it.

also once the nightfall quest is completed it than open movement or do i have to do that quest again to come back from nightfall?

thx
