I seem to remember doing a bunch of sketches in a notebook for the Proclamoid’s design and nothing worked until I settled on “basically just a sphere with 3 eyes”.
Transcripts
Proclamoid: Passcode.
Tachelock: What is this thing?
X2: I don’t know.
X2: It was hanging around outside the bar when I arrived.
X2: Then when I opened the door it just floated in here and started asking everyone for a passcode.
Mechra: It’s a proclamoid.
Proclamoid: Passcode?
Mechra: And unfortunately, it’s probably here for me.
Tachelock: A what?
Mechra: Proclamoid. No doubt sent to deliver a formal proclamation from the glorious House of Nex.
Mechra: Although how it tracked me all the way to this dank little corner of creation is a mystery.
