Deenglows (Wyvernus kyanos) are the holotype species whose subgenus is named in their honor. They are cerulean-scaled wyverns found on Gaia. They are closely related to the Flapbeats of the Gold Saucer Area, the Wind Wings of the Whirlwind Maze, and the now-extinct Euotu'n. Several have come into the ownership of the Gold Saucer Battle Square.
They hold their body upright, like a seahorse, with their tail curling slightly underneath and their neck curling over and forward. Their wings are held outwards and splayed out to the sides. Their legs dangle uselessly while they are in the air but are presumably used to support their weight when they land to rest or feed.
Their wings are quite sharp and are used as their primary attack method. They seem to be attracted to graviballs, which may grant their immunity to gravitational fields or allow them to utilize gravity magic themselves, if not both. Ether is also usually found in their vicinity but it is not known why they carry this.
Because of their emaciated frame, they are easily disturbed by wind attacks; however they have adapted well to the cold and can even absorb cold energy and ice magic. Their powered flight grants them immunity to gravity and they are able to also resist lightning.
