Rigorous

Rigorous is a participant in the Secret Challenge. He/She has been involved from the beginning and is actually quoted by Rashid as being the 6th decimal in Peculium.

The path that led to this clue originated from a clue left by Rashid in the form of a picture: This image was posted with the comment " I UM 3 6 9 E V E " and had a file name I.U.M.3.6.9.jpg

The image is that of a quetzal.
