Who will win? Nomi has incredible skill of battle mediation but I don't think it's going to be useful in a 1v1 fight, her Sever Force ability is a good feat. Satele got incredible Force and lightsaber skill but nothing too special.
The arena: the known galaxy.
No other helps, just 1v1 duel to death.
As for the battle meditation, I think Satele Shan has that to. So.... yeah.
But I think this would be a very close fight. It's hard to say who would win. I have a feeling Sunrider would win this one.
