AB, I am afraid you are at the mercy of The Fair Lady, here. While her sheet is not complete, the OP states:

[quote=The OP]Spine of Iron [ X ] - Temporarily Locked - The Fair Lady[/quote] 

It does state within the NS construct that you should check these things beforehand. But as your sheet is complete, you leave me in a sticky situation.

My verdict? TFL gets to choose, as she has a claim. If she wishes to allow you to share the Plane, so be it, I can adapt to that. If not... well...
