Your a spirit, now that avatar Korra left both the north and south spirit portals open, spirits can freely enter the human realm and humans can freely enter the spirit realm. You started walking around Republic city, when you spotted an apartment complex . It wasn’t anything special but you decided to enter it and explore as they don’t really have apartment complex’s in the spirit world. You walked around the small complex, you walked past rooms 97,98 and 99 and found a communal laundry room in the basement. Boring. So you walked back up to the second floor and sat at a door which was labeled room 101. Someone opened the door and froze.

“Oh. Hello there spirit creature. Could you move? I need to get to work.”

you saw her badge and realized it’s the chief of police Beifong, of course you didn’t know who that was being a spirit and all but still.
