Which one of Fallen London’s items is your spirit animal (you can define this in whatever way you want)?
I hate to be utterly unsurprising with my answer, but for me, it’s the Insatiable Gloves.
To be painfully obvious, I’ll go with Numbered Antler-Fragment.
Ngrooooo.

I’d say the Semiotic Monocle. A glass that helps you understand symbols without going insane. I could really use one of those.
Probably a Coincidence. I connect with it on a very spiritual level.
And if Sunless Sea “items” counts, the Comatose Ferret. That would be quite literally me these days.
Blackmail Material, without a doubt.
It’s just so convenient to have that!

I’d say “Certifiable Scrap” is a fitting descriptor for me. Possibly “Extraordinary Implication”, but I don’t want to come off as boastful.
Sneak-Thief’s Mask
can this be an actual companion? if so then it would be the devious raven adviser who i lovingly named varys
hes just been with me so long as an ally and friend even not counting pre transformation era.
now if it had to not be an ACTUAL animal then it would probably be the unobtrusive bowler hat i was given so long ago and has been kept safe ever since even now as i mingle with the great and the good.
A Copy of my Tragedy of Romance.
A Move in the Great Game.
An Illicit Volume of Unexpectedly Racy Fungal-Themed Poetry.
My Bitter Saker Falcon.
Terrifying Candies.
Whirring Contraption.
It’s even conveniently animal-shaped.
Pair of Scarlet Stockings of Dubious Origin.
NO NO NO NO NO NO NO (YES) NO NO NO NO NO NO NO
A Surprise Package. Mystery, hope, anticipation… disappointment.

Silly, yet sinister. A delicious fantastical concept, unafraid of not making sense. So much richer if you know the lore. It is Fallen London.
I love all these answers. For me, it’d probably have to be the Faded Morning Suit, which currently serves as my profile picture. It was one of the first items I purchased after arriving in Fallen London. It’s a reminder of simpler times and humbler means.
