gladiators defence?????

can my factions warrior get gladiators defence since its in dragons lair u have to ascend to get there. is it possible to get there with my factions warrior and if so how please help

Just go ascend and get it.

However if you didn't link prophecies with factions I think your out of luck

If you have Prophecies and Factions merged, you can take your Canthan chars to Lion's Arch from Kaineng City by boat (speak to Guardmaster Chienpo for the quest Chaos in Kryta, think that's his name anyway). Once you've crossed over just make your way to the desert missions, either by doing all the missions on the way or running to Sanctum Cay and just doing that mission to take you to the desert.

ok thank you
all im in desert now about to do the missions there hope it works
