[@Prince of Seraphs] I think Sini would accompany it back -- after all, Spring has a duty to see that it's delivered safely, and ensure that it actually reaches the Winter Queen, and return word to Nyx.  I see no reason why a single guard or even a small squad -- such as Sini commands -- might not be permitted.  [@Belle] would need to verify, though.

Yes he would send a small guard along with the convoy and if you wish Sini to accompany it I don't have a problem with that. Simply put though Sini wouldn't run across Arys by accompanying the convoy.
