I was going thru the net studying Asgard and ancients, and I found an intresting picture of what is rumored to be part of Atlantis episode or part of an Sg1 episode involving atlantis. It seems as though the Asgard were some how defeated by the replicators but managed to increase the gravity of a star nearby the new replicator homeworld, and used the trigger i nreese to once again "come forth" as all the replicators came to the homeworld of replicators the asgard blew up every planet and sun located near the homeworld. This destoryed the Replicators, but had left the asgard homeworld also destroyed by a replicator bomb planet from the season 8 premier of sg1. The replicators are now completely wiped out and the asgard are struggling to rebuild. The Asgard had finally cloned their ancestors and begin reproducing again, however the Asgard are in search of a new world to rebuild their empire in our galaxy so this way they may be at assistance more often. The Asgard plan to terraform mars and place a stargate there. after scannign the planet for life signs or powersigns they discover several things. Within the mask on the moon are several million ZPMs over 200 puddle jumpers, a few hundred other ancient ships and several diffrent types of stargates(rumored to be 4) There is one more thing it seems the mask is not merely a base but an actual ship(like atlantis) and it has the power to terraform mars. The asgard and SGC are delighted and decide to share all of the technoledgy except the asgard amke them promise not to use the technoledgy unless absolutely neccessary. The Asgard allow the SGC to take a few dozen Puddle jumpers, but in return they must help the asgard be armed for possible gou'ald attacks or for attackin gou'ald on foot, and no one can use stargatres going to another galaxy except asgard. The asgard open the pegasus gate and gate to Atlantis to tell them and to give them power to either come home or kill every last wraith. Problem is the sudden shock has started a 3 way war, Earth vs Atlantis vs Asgard.
