Could you imagine if every delicious friend got their own unique weapon? That would be rather mad, but also a very fascinating high donator reward for sunless skies. My own ideas for items

Possible Opportunity Card drawing because of the Spirifer
Off the hook... or rather fork
Oh dear. It seems your Spirifer has had a rather nightmarish dream and is trying to resort to the only thing he knows well: stealing souls. The only problem is that he's trying to extract the souls out of your animal companions.


Talk some sense into him (persuasive challenge)
Come now friend settle down. You can't extract souls from animals, that's ridiculous. Look here, you already have souls.
Success: You calm him down with words of reason. He goes back to his bottled souls and gives you some as a gift before falling back into his tormented dreams. Reward: Persuasive is increasing: ?cp You've gained 45~100 Souls.
Smack some sense into him (dangerous challenge)
You can't let him extract the souls of your animals. You don't know if he can. You don't even know if animals have souls. But no doubt that fork is going to do damage to your prized companions.
Success: A quick blow to the head and he's out cold. He's simply sleeping don't worry. On his descent to the floor some brass fell out of his pockets. Reward: Dangerous is increasing: ?cp You've gained 90~200 Nevercold Brass
The Starveling Cat! (unlocked, of course, with the starveling cat)
Oh dear. Oh no that's no good at all. You don't give a d**n about the cat, it's your spirifer you're worried about.
I think this might be a single output storylet or maybe a matter of luck. I'm thinking you either lose the spirifer and gain some dark knowledge, or your spirifer is changed into a Raving Spirifer: He only whispers, mutters, and screams one thing: The Name. IDK though since I didn't create the starveling cat and I don't know the writers' intentions with it.
