Forge of gods will a counter part with the vex illegible dlc. My belief is, the vex raid will be about opening a gate leads to the forge of gods in mars, this forge is, however the last ahamkara, Since they grant wishes, it would make sense. The raid would be about mercy killing this dragon, and the story missions would be about how they captured and how they used it. I would so love to work for bungie, i could make better dlc in my sleep!
