Proteus, Morganella and Providencia Group.

Not sure if it will appear the textbook swarming if given more time to grow or that is already a swarming growth pattern so I'm leaning on to Proteus mirabilis.

Proteus is beige on CHROMagar.

Take a step back and read the clues again.

My first guess before E. faecalis was S. bovis

Buzz words like landlocked made me weirdly associate it to the word "cattle", there's no rationale why it just is. It's the same feeling when someone mentions penicillin and I think of oranges but never the other way around.

Then the word saline which is used at 6.5% NaCl growth to test between Enterococcus spp and S. bovis. This is all not factoring in CHROMagar. I'll read on it further.

S. bovis is also blue on the agar, but they have a different appearance compared to Enterococcus.

The organism in question is gram negative.
