Sally, Amy, and Creme.exe were roaming through the the corrupted forest, and eventually bump into you. They look at you and try to assess who you are, be it friend, or foe. They are under the commands of Xenophanes (Sonic.exe), and have been ordered to kill anyone that's still alive.

Sally "And who might you be?" She says with a somewhat dark voice. Cream just hides behind her, while Amy draws her hammer just in case.

You can be an Exe, a Mobian, or another entity like Xenophanes
