help!!! can't find emisora's bones trigger point!

hi guys - i am doing the 'weeping of the ruins' quest for the floating island attunement and i have searched all over the ritual area north of where the priests are gathered, as per the lexica instructions, but i am not finding the trigger point and the ritual master is not appearing. i am stuck until i can fight him and get her bones back.
can anyone out there be more specific as to where the trigger point is?
i appreciate any assistance!

never mind, instructions sohould say in the area of the priests!! quest trigger found and bones obtained! will make an update when i blog the quest.

Trigger points really drive me insane. Glad you found what you need.
