Yeah, the Hestia's original tech description had it as a mining cargo hauler that was refitted into a population carrier during the Exodus. That original description didn't sit quite right with me, especially when I saw that the Hestia is referred to as a "liner" ship. So I thought, "what if the Hestia is really just a 24th Century version of an ocean liner/cruise ship? Wouldn't that make more sense than a converted cargo hauler for carrying a bunch of civilian refugees?"
So I did my go-to move: I went to Wikipedia. Fun fact: it turns out that ocean liners
and cruise ships
the same thing. It turns out the former are just for ferrying passengers across long ocean distances while the latter are specifically designed for ocean vacations
that also happen to include stopping at vacation-friendly port cities.
So I made the Hestia a Freespace version of an ocean liner (and not
a cruise ship) that was refitted during the Exodus to have more armor and defenses as well as an additional hydroponics bay to (help) feed the Exodus Fleet. I think it just makes more sense that if you need a big ship to carry lots of civilians, modifying a passenger liner (which is already designed to carry lot of people) is easier overall than converting a large cargo ship (which is mostly empty space that requires a lot of additional facilities [sleeping areas, bathroom facilities, eating areas] to house large numbers of people). I could be wrong, but that's just my $0.02.
So someone goofed and misspelled "Denoran" as "Demoran"? That's strangely fortunate as I might have missed this oversight otherwise.
But yeah, Nyct, the Hephaestus-class factory ship ORFS Demoran in-game remains unchanged. (I ain't gonna borrow trouble! I got enough to do as it is!)
