Complete Mission 03: Massif Contamination
You will pass this Cie'th stone on your way to the mark for Mission 04. Once that Mission is complete, you can backtrack to activate this one. However, you may want to continue on to Mission 06, completing it and Mission 07 before this Mission, to save yourself some travel time. In any case, The Tsumitran Basin is more dangerous than this mark. The Edimmu can be found in tiny side path from the central part of the area. This is a pretty simple fight compared to, say, a Behemoth King.
