Senegalite was one of the finest fortune tellers. Her visions were always accurate, she was never wrong. But her only purpose were telling only good news. Once she forseed something awful to a Diamond. Then she was harvested and placed in fountain statue. Over time statue broke, but not entirely, and since then her body is half statue, half her light form. She still can help with making decisions or forsee something in near future, but since sapphires took her place she is rarely visited by other gems. If you look into the water next to her knees you can see what will happen to you in near future.
Her eyes are blinded by piece of statue, but she still can see you through her gem.
Her voice is probably the most soothing voice you’ll ever hear.
She was very kind and helpful when she wasn’t trapped inside the stone.
She can’t be pulled out from the statue, because she would instantly go corrupted. Statue need to fall apart on her own, then she’ll be free.
When she wasn’t trapped she had really weak power of water manipulation.
