This may seem a little stupid but hear me out. neither gate goes into the future, they both go into the past, but at different times in the past. you would know this if you read the grimiore. the "venus" one or right one is the farthest in the past, and the other one is still pretty far but closer to the present. ever notice that large pillar, or pedestal, in the "mars" time zone that is located- when you step into the timegate during the gate keeper part, then turn about 40 degrees to the left and forward about 3 or 4 meters- that one. Also when you go into the "venus" time zone that pillar is completely non-existent. Also the same pillar is much, And I mean MUCH larger in the "present" than it is in the mars time zone. We all know that destiny takes place in the future, so what if the developers were referring to REAL world time when they said that. Thus I propose that when they reffered to the future they actually ment the destiny present, and the past is the venus age. this would mean that mars would be the present to us, but to destiny it wouldn't be the present. this would make it the place between future and past but not the present, not the destiny present. back to the pillar or "pedestal", what if after the raid and you kill aethon you have to enter the mars time zone and climb to the top of that pillar or "pedestal". I know it seems abnormal, but think about it.
