[@Prince of Seraphs] Putting Sini in Winter permanently was not what I had in mind.  And realize that she'd feel very torn -- on the one hand, she prides herself on being an excellent adviser. On the other, if she advises Winter too well, it may cause problems for Spring.  *shrug* I think she can manage that as long as she still gets to move freely back to Spring when she wishes.  So she'd be splitting her time between the courts.

I believe that would depend entirely on the kind of advise she gives. Regardless though you may be overestimating how much the Winter Court would value her input.

If you don't want Sini to do it Nyx can always send someone else.
