From the Weaponsmith, turn behind you and you will see the high mound upon which the Temple of War rests. There is a large group of Shadow Army units gathered at the bottom of the ramp and then in the middle of the ramp there is a group of Shadow Mesmers and Shadow Monks. The large group can be avoided, and also, can be lured into a fight with the nearby Skeleton Army patrols. The Mesmers and Monks can be taken out with well placed AoE spells. Once they are cleared, the gate will open into a circular area with ramps leading up to a platform.
