Sonic, Tails, and Knuckles stood for a moment, staring blankly at this sudden arrival. Knuckles spoke.

"So why should we trust you, then?"

"It's quite a story. Do you want to know?" Equinox asked. All three nodded.

"Well, I assume you know about when the chaos and master emeralds came to existence, yes?" They all nodded again. "Well, when the master emerald itself formed it's negative energy was shattered and reflected, casting the bits of energy across the world. If all 6 shards of energy are gathered it will form into the dark emerald, capable of controlling both the chaos emeralds and the master emerald itself. Now, this dark energy sometimes makes itself an uninvited guest in a person's body..." Equinox pause and looked at them, all of their faces in utter shock at the information, especially Knuckles. "Anyways, when I discovered several months ago that something wasn't quite right with me I looked into it and found this information and realized that I housed one of the shards of energy. Signs of it are an unpleasant buzz every so often..." Tails and Knuckles gave each other and uncomfortable glance, "And finally I have discovered that people with shards of energy can track each other, kinda like a mental radar... Do you follow me so far?"

"Wait, do you mean to say that Knuckles and I have these shards of energy in us!?" Tails was worried and excited all at once.

"Ah, yes, that is so... But I just wanted to warn you. I know someone is trying to make the dark emerald. Someone who also has a shard. There are ways of extracting energy. The quick way is excruciatingly painful, the energy being ripped out all at once. The near painless way takes about 6 months though, so whoever is trying to put this thing back together obviously wouldn't wait six months."

"But how do you know someone's trying to make it?" Sonic questioned.

"Because I was attacked by robots which I discovered by looking at their remains would have had no way to track me other than by following an electric signal, the shards produce such signals, much more powerfully than the natural dull current that all living things have." Equinox told him, "I just thought that it is important for you to be on full alert..." She started to turn.

"Hey! You're not leaving now, are you?" Tails shouted, "If you leave we wont have a clue about what to do! You're the one who knows so much about it."

"Well... I suppose so long as I can't pick up anything else, I'll stay and help you out." Equinox said.

Without warning 10 robots with red arms and legs dropped down from the surrounding rooftops, all armed. They aimed their guns at the four, but did not fire.

"The same robots that attacked me!" Equinox exclaimed. "Enough of this." She dashed forward with a speed that surprised Sonic, Tails, and Knuckles and shot a fist out at one of the robots, green fire trailing after the fist. The robot's body dented horribly and it fell to pieces. Equinox didn't stop there as she delivered another punch to the next robot, then as she came to the third she made a diving motion, attacking with both fists head on. The robot shattered like glass on contact as Equinox flipped and landed on her feet, but suddenly became aware of the six eyes watching her and turned around to face them.

"Oh, I'll get these last ones." Sonic said. He jumped and used his homing attack, smashing one, two, and the third and final robot. "Come on, let's not hang around here..." he said. The four of them dashed off.
