Panel 1: Tamamo Cat, a female servant with large fluffy animal ears, wearing a large bow to tie back her hair and a large leather collar around her neck. She smiles as she says to an unknown figure, “So you’ve finally come this far Master… /I didn’t expect my scene to come so soon, I guess you’re after my paws?”
Panel 2: Tamamo cat smirks(uwu) expectantly and chuckles. Her collar is shown to have a large bell hanging off of it. Her enormous paws wrapping around her body are partially hidden in her sleeves and the claws are fully extended. Ishtar is partially viewed in the lower right corner, an amused look on her face with a small text above her showing her response, ‘Finally?’
Tamamo Cat!!! Those paws! Must squeeze the pads! Why don’t we get more of you?

I made a mockup of what I think Miskatonic’s seal should look like
the element in the back is the Star of Ishtar, the shield has no special significance, and the symbol on the shield comes from alchemy. I used purple, gold, and black, partially because I think that’s just a nice creepy color palette.
