The bedroom of Nami’s forest cottage is decorated with a single picture hanging on the wall (aside from the flower patterns all over the place, of course).
According to Nami the picture is old but magically preserved to ever appear as freshly painted. She cites the historical records, telling that the author was inspired by an encounter with a winged messenger at a huge evergreen forest, which used to be called the Emerald Garden.
No-one knows who the painter actually was. The painting was found in the forest, apparently in the same place where it was painted, with a short description in poetic form:
At the first light I saw her
reaching for the dew-laden petals,
feathers gently dancing to the rhythm
of mild morning wind.
