This is 0% based on factual evidence, just so you know. Awhile ago I had a dream. I was a Guardian in a 6-man fireteam, and we were fighting a dragon. It was underground, it rose from a pit of lava, and there was alot of fire everywhere. So this kind of got me thinking, and I can sorta see Forge of Gods going like this: The Last Ahamkara is the main antagonist of Forge of Gods. Its angry with mankind for wiping out the Ahamkara, so its sided with the Cabal to get revenge on us. It shows them the Forge of Gods, a powerful artifact buried deep under Mars which can grant untold power to those strong enough to use it. The missions would have us hunt down the Cabal command and intelligence to find the Forge, and the strike would pit us against a Cabal general who used the Forge. The Raid would have us delve underground to find the Forge, and we would use it to kill the Last Ahamkara as the final boss.
