I'm currently mapping a Starfleet ship on Roll20 using the official Modiphius TNG-era tileset. These tiles are, to my knowledge, not labelled in any meaningful way; the following image is listed as "5x10_ST-FED-HT_8".
This caught my eye; it looks familiar and I'd like to use it in my campaign, but I can't name it or its purpose.
Was this room ever explained on TNG or in a related technical manual?
