Parabolan Panther
From Fallen London Wiki (Staging)
There is a section entitled:
Your Parabolan Panther requests your assistance
She leads you to Veilgarden, then into the prop-littered alleys that snake behind its music halls.
You unlocked this with a Parabolan Panther (you have 1 in all)
I note the relevant section is included for the society card
