Sand poured from the small holes in the ceiling. Dio sat on the floor. Around him was the ruined main lobby of their fortress. Ever since he returned from Middlemist, he worked on getting the fortress in an upright position. The collapse and build-up of sand skewed the 'ground.' Right now, the fortress was still buried in the sand. The only passage was the one he made on his way here.
However, that passage must have collapsed as well. Nothing permanent stayed within the shifting sand.
Dio had his eyes closed. He breathed slowly as if meditating, letting his body faintly shine. In his mind, he recalled every day he could. He wanted to remember everything about his stay in Middlemist after running away from his father. Most importantly, every little thing about Fenris.
