In the Milky Way galaxy an Asgard ancestor is discovered so a lab is set up on Adara II, a protected planet for Heimdall to study the ancestor in order to try to learn a way to fix the Asgard cloning problem. Anubis learns of this and dispatches Osiris with two upgraded Ha'taks to capture the lab. Learning of this, the Asgard send Supreme Commander Thor with a Bilskirnir-class ship to defend the lab. This is believed to be enough to enforce the treaty as the Goa'uld ships in the past haven't been able to match a single Asgard vessel and the rest of the Asgard fleet is busy engaging the Replicators.
