With the spell finished (at least on his end; the lights continue to bloom across the available surfaces for a bit longer), Lahabrea is more than willing to turn instead to the discussion of how the magic works. Not for nothing has he spent much of his time in the halls of Akadaemia Anyder, after all. To say nothing of the fact that he has spent so much of his life focusing on the ins and outs of magic.

(Creation magic, mostly, true. But that makes him no less qualified to speak on any other sort of magic.)

"You may."

There's a nod with the answer, before Lahabrea gets on to the actual explanation.

"All magic is born of aether - an energy that exists in abundance both in my own world and within all living beings. It is through concentration and focus that aether is than shaped into whatever one should wish. A simple spell, such as a simple elemental spell, or that which has created these lights takes but a small amount of aether. A larger spell, such as that required to shape furniture would require both more focus and a greater quantity of aether."

A pause, and then he continues.

"However, as this world is not as replete with aether as my own, I am limited to that which resides within my own body."

Which is no small amount, not that he says as much.
