(I recommend being Tikal, or apart of the echidna tribe. This takes place 3,000 years ago.)
Worshipped by the knuckles clan. Or...should have been. That clan was war based. Only power hungry fools, it seemed. Once mere ruffians that didn't try anything thanks to the previous chief being more pacifist, and thus made sure the clan didn't try anything. Then came the next guy. Pachacamac. He turned them into warriors. Warriors and bandits. They were prospering now. Expanding their borders. But they wouldn't stand a chance if Chaos chose to intervene with their...current ways.
But there was one, it noticed. One that wasn't like the others. One who's gentle nature seemed to make even the Chao he protected curious. They seemed to have begun to trust her. And it looked genuine. And if that wasn't enough, she server entered the inner altar. That was where both Chaos Emeralds and Master Emerald laid in wait.
This was an immortal god. He didn't plan to make himself known to the Knuckles clan, nor act until it needed to. It has its priorities. Protect the Chao and Emeralds. But this young Echidna, currently petting a Chao like they'd known each other for years, just might become something else to defend. Maybe.
If push comes to shivering, all it needs to do is absorb the Emeralds, and it'll not only change its form, but get stronger.
