Umbral Decoder — Hold Up, Guardian!

As you approach the Umbral Decoder, Drifter's pre-recorded voice plays from its tinny speakers.

"Whoa, there! If you're hearin' this, you're touchin' my machines in the wrong order! There'll be plenty of time for decoding later, but now you gotta check out the Recaster!"

You look over at the Drifter, who can barely contain his joy. "Gotcha, Hero!" he manages to say before dissolving into peals of laughter.
