For Asgard!

In the back of Sif's mind when she had made the decision to return to the Nexus - pleased that the door was still to be found where she had left it, if you could leave such a thing - there had been the conversation she had had with Natasha as a man. After being well rested, well provisioned and no longer feeling the gnawing need for more time at home, Sif was ready to go on proper adventures. Moreover, she was excited to do so without her usual companions, but instead with a new friend who much to her delight was also a woman, as well as a fellow warrior (in her own way that Sif could not pretend to fully understand so far). Natasha had told her of a door leading to an island with pirates and handsome men - and Sif was very much looking forward to whatever good times they might have in such a place.

A few days after returning to the Nexus, having established herself again, happy to have bonded with the Captain - Steve, his name was Steve - and mildly concerned over Loki's absence, Sif was finally fully ready. Clad in full armor, with her shield and weapon at her back, Sif had gone knocking on Natasha's room door very adamant that she drop everything and come show her where to find the door leading to the pirates.

And Natasha had accepted Sif's request!

Finding themselves right in front of the required door, Sif could not deny (but would, if asked) the nervous trembling in her stomach as she prepared to embark (perhaps literally) on a completely new adventure. Yet another one.
