Walls
The steps were cold under her hands as she walked upwards, and at the top, she bent backwards until her feet touched the landing and bounced up to stand on them instead. "Hi Azula!"
Azula shifted her heavy robes and glared at the blank wall beside her. "Leave."
Up there, it was cold even in the summer, and her armor felt like ice, pressing in on her. "Sorry." The heat from Azula's flames licked at her as they scorched past. "I won't tell the guards if you don't do that again."
Azula had stone and metal pressing in on her.
Coming and Going
Azula dressed in robes, and when she was angry, her nails bit into and cut the silk. "You're never here when I want you, and you're always here when I don't!" Flames gathered, but she squashed them. She didn't want the guards to come.
"I didn't think you ever wanted me here."
"Don't be stupid, Zuzu." Him there without her... That would have been nice.
The door didn't open or close, but all that was there with her was empty room. Not being able to tell him when to leave and when to stay was the worst thing about it.
Hush
When Azula opened her eyes, her mother hovered against the stone wall like a smear of bright blood. Azula's hands clung to her arms so hard rivulets of blood joined her mother on the stone. "NO!" She howled, "You're not supposed to be here; you're not real!"
"Azula," she whispered, moving close and running her fingers through her daughter's mangled hair, "It's alright now. I'm really-"
"No you're not; I know you're not!" Her eyes slammed shut and she clutched her arms tighter.
Unwillingly, Ursa slipped out and locked the door behind her, her footfalls echoing dully on the stairs.
