Level 35 Job Quest (Warrior)

I'm not sure if is for every job or is warriors only, but for level 35 job quest we're required to kill Giant Sandworm in the quest Embracing the Beast. I followed the quest arrow to a red area only to find nothing there. After I waited for half an hour for it to maybe spawn, I walked around Sagolii Dessert where the Sand Worms are but with no luck finding it. That's when i decided to google it and find this http://ffxiv.gamerescape.com/wiki/Embracing_the_Beast. Anyone done this before and can give me a tip on where to find the Giant Sandworm?

I am pretty sure it's an interactive spot to force spawn the thing, not a world spawn. I finished WAR quests up to 50, and every mob I had to fight was a forced spawn in one way or another.

you need to stand near the destination thingy so the boss will spawn thats all
