But the 'Battle Star Map' was something that, if its true potential were realized, battlefields would become a playground for the Oracle...
It is a powerful ability that one wouldn't want to go against, regardless of how daring they are. Klaus and his team may be getting their way now, but if she had even unlocked a sliver of her true potential, they would have found themselves in hot water by now.
The map came in different levels, each level representing a warrior on the battlefield. The white stars were mostly on her side... they represented the team she was fighting for, or the team she had chosen to aid.
The black stars were those she would be going against. She could interact with the flow of the battle around the black stars.
They were the easiest to handle. She could assign more white stars to ambush the black stars, provided she had enough white stars to spare.
In the ongoing battle, she did, so the black stars weren't having a good day at all.
