Shanifa has told me about the way the Temple sees her as an individual. The Temple sees her as this mysterious individual who knows everything and controls everyone behind the scene. She has also told me that the Temple had spent a lot of effort to figure out her identity but failed. If it wasn't for the fact that she decided to reveal herself, it would never know where she was.
That means she proposed the idea of establishing an alliance with the rest of the human Kingdoms. It ends up being useless, though, since she immediately "turned herself in" after she implanted the Eye of Causality. It told her that the plan she envisioned would never be realized because of my existence.
You may wonder why the Temple became the leader of the alliance if Shanifa (Cresundia) was the one who proposed it. The reason is Solas, the King himself.
