Ideas I like so far,
"The Last Words", a little awkward off the tongue sometimes, but good.
"The Sanguinary" would be neat, I know someone suggested something like that, alternatively 'The Sanguine'?
"The Bookenders" might be good.
"The Ghostwriters" is a great one. Prolly my top pick out of what's been given so far.
"The Epilogues" sounds cool too.
No a fan of,
"The Faculty", not unless there is something about two of the crew that makes more sense. Aldo seems to be the only one who kinda follows that theme.
"The Scholars" is again a little too off from their theme.
Any name that is in Latin. Dunno, just doesn't ring right in this setting for me.
Maybe go with a menacing business name, seeing as they're 'Professionals' and such. Think 'Wolfram & Hart' from Angel or something.
'The Sanguine Hand'
'Blackwater' (appropriate for the setting, also a merc org IRL)
