Red Letter Location

So I know that there are only 7 known red letters/envelopes so far, and in the orchard the gardeners shed has a gem holder that all the other safes had, and in his little book he mentioned wanting to get the statue of Rynna in the cloister as it's only right. Well I upgraded the cloister to be Rynna, and on the back of the statue there are four letters, each in a corner, C in the top left, X in the top right, E in the bottom left, T in the bottom right. Does anyone have any clue what we can do with this? Hoping to find the final letter soon.

Those letters are there regardless of the statue I'm pretty sure, the default statue has them as well.

Yeah, those letters are part of a different puzzle. I don't think the gem holder belonged to that same gardener, but maybe?
