It also completes it for anyone who happens to be in the vicinity of you when you complete the central simon says thingy and the [url='http://www.wowhead.com/?quest=11059']rock dude[/url] comes out.

Horde love to cluster near me when I do the simon game.

As per some wowhead comments
Actually, Bawsderitchy is partially correct. You won't get a quest complete if you are near someone using the smaller crystals. However, if you are near the monument when a *group* is using the larger crystal to summon an apexis guardian, it might happen. ( see http://www.wowhead.com/?quest=11059 ) I say "might" because it appears the group has to successfully complete the entire lighting sequence. I discovered this myself when I was running by a monument as a group finished. They weren't even my faction, but I still received the "Apexis Enlightenment" buff and also a complete for "The Relic's Emanation".
