Help finding an avatar?

Hey guys, once upon a time, I found this really cool blind dragon avatar where the only way you could see things was by touching things with your hands, or by using a special cane, but I lost it when this mechanic broke. Now that it’s been a while, I was hoping I could check it out to see if it’s been fixed, or if there is anything like it. There’s just one problem: I don’t know where to start looking, so I figured here would be a good start. If any of y’all find something, please let me know. Please and thank you!
