This may have been in the game before, but last night I noticed that there is a path winding up the hill in the area where your ghost says "We've woken the Hive!" during the darkness something or other mission on the moon. At the top of the path is a banner, which a friend of mine says is commonly used to indicate starting points of strikes (and I think he said the raid too). Has anybody else noticed this? Has this always been there? Could it be the starting point of the next raid? Might make sense since it's outside the Temple of Crota and the raid is called "Crota's End".
