Coriander was correct in his assumption. As he stepped threw the door, Arlan made a gesture with his finger, turning it in a circle in front of him, as he left his breath for the brief moment required for the spell to take affect. Then a moment later he was conferrable, warm, and back in the original form that his guest had seen him in -- and snug as a bug inside a study bubble that was large enough for him to sit comfortably on the "floor" of it.
Now this was a wondrous treat -- even for the fae. Neese, or Arlin in this moment, was a surface being as sure as any other creature that walked on two feet - or four. Thought he prided himself in tilting the world to his whims, he also knew his powers and abilities were not without limits - and that there were certainly secretes in this world that he hadn't discovered yet, and likely some he might never discover.
He'd been in the ocean before but certainly never drifted under the waters at the suggested depths of this room. As his bubble drifted past some kelp, the fey lord reached out, threw the wall from his bubble, which sealed neatly around his exposed limb and brushed his fingers against its length, and when he pulled his arm back in, well, he was as dry as he had been before they'd entered the gardens to begin with.
"I must complement your father's creativity and his mages," Neese said, not bothering to hide his surprise or wonder, "this is impressive on scales I usually wouldn't expect mortals to be measured on." He had always believed, even as vain a creature as he was, that acknowledgment of achievement should be given where it was due -- very little of the mortal realm impressed him for more than a fleeting moment, but this was there with those few things.
