This is an image I got from an artist who goes by the alias "AgentElrond" a long time ago, all the way back in 2008.

I had managed to snag a screencap of her 10K kiriban on DeviantArt, and at the time I was trying to come up with an entirely new appearance for my online persona. I decided to take the opportunity to ask her if she could design one for me, with my only request that it would be an anthropomorphic, ice-elemental serpentine dragon. She thought that the "anthro" part would look odd on a serpent though, so she omitted the the legs in favor of a more naga-like design.

Despite the deviation from what I asked for, I couldn't complain! She did a wonderful job on this piece of artwork, and upon seeing it I decided I would use it as my avatar anyway. And thus was the current iteration of Visimar, both as a persona and a character, born.

I have made a couple minor tweaks to his design since then, which I do not have an image to show off yet, but he has remained unchanged otherwise. Perhaps some time I'll approach her for a commission of Visimar with his updated appearance. For now, I would consider this the most accurate envisioning of him.

Credit must me given to the artist for this wonderful piece of artwork! If you wish to see more of her works, check out the links below:
