Was That There?

Grey and Alice walked over to read what was written on the wall, but it was in a language they did not know. 

"Do you know this?" Grey asked the others that were there. 

The bunny was mysterious and should've been in this place before them, so Grey felt it was best to ask it since there was a probability that it would know. 

'How would I know?' The bunny leader looked at him oddly. 

Grey could only give up, however, he didn't forget to write it down. This was probably valuable information. He didn't know too much about ancient times, so it wouldn't be bad if he could decipher this. 

They continued trying to open the other doors. Three more opened but just like the first one, other than chains and skeletons, there was nothing else.
