Dang. Maybe shoulda gone with someone smaller, oops.

Duchess Arethia, 9'1" at the head, 19'10", and with a tail that fat I'm sure she'd add quite a bit.
5'6" human for scale in the first picture.

So they have a second Twitter account which I think they're trying to be more active with. Here it is:

Here's EmeraldCasino's page:

Oh, if only. Unfortunately, Callula doesn't live on Earth; the oceans are too small to contain her there.

Flat colour version of the sheet. Also, a fun fact, she did not use to be this large. It's all mixed up in that reason she's no longer welcome in the Underdark.

Well, if multiple are allowed, I've got four here.
Toss - 3 feet tall
Rumble - 7'3"
Synthia - 6'9"
Jugs - 6'2"

If only one is allowed, I submit Rumble (or Jugs if you'd rather not).

Of course, even with the aid of her Dragon Slayer, Gloria can't get everything done on her own. Here she is depicted showing her appreciation for one such helper, with some rather unintended side effects of such appreciation.

Due to just how large she had become, it was deemed necessary to let Gloria continue her work, lest she be left immobile. Despite her chest making the piloting of her Dragon Slayer more cumbersome, she is considered one of the best Silver Dragons.
