Well as I was on my way to Ojaveda in search of a tavern when I came across some quicksand, though seems to be selective on who sinks into it. A human ran ahead of me with no problem, followed by a another Klyros when the Klyros disappeared into the ground. Not having had any problems earlier I dared the area where the Klyros disappeared but did not seem to sink.
Well the quicksand can be found after the T-intersection in the forest to the left (right to Mage house and mining area) to Ojaveda. The path in the forest makes a right turn, before existing into high walled rock outcrop. At this point the quicksand is located.
So be carefull at when existing the forest to Ojaveda.
