Whisper of the worm

[junior bison]

Is there a way to get whisper of the worm other than from the exotic archive cause I don’t got an exotic cipher till next week or is there another way to get exotic ciphers other than xurs nightfall quest

Just the Season Pass and Xur quest but that's it.

And it isn't even a Nightfall quest specifically (idk if it was in the past). It's just completing strikes
