In a train to a friend's place for a couple days.
Amusing myself by thinking about Termrean dragon (Arcanth's and Xaranthras's people) vocalizations.
Being so tall and having just So Much Neck and Lung, their voices are usually pretty deep and weirdly hollow sounding (I've heard what cassowaries sound like and that's just something permanently stuck in my head now).
They don't really growl or roar naturally, though an angry Termrean will hiss, which can get disturbingly loud, and they can make shrill shrieks similar to elk calls when keeping in contact over long distances.
However, since they do have quite a bit of vocal flexibility thanks to their ability to speak, so in the same manner as death metal vocalists, they're technically capable of learning how to growl.
I just want to imagine Arcanth having learned that from the dwarves who raised her, and demonstrating these skills will impress every cultural dwarf in several miles radius. Xaranthras keeps being disturbed by his antics.
