The "nun" is commonly called the unicorn in 3d games, and I think it's reasonable to extend that name into 4d games. (Do you have a good reference for the name "balloon"? I've only ever seen it called that in one place.)
The initial setup is interesting; all the pawns are protected--many of them by the army of balloons--and they smother many of the initial lines.
I don't completely understand the pawn movements.
