Seimi is currently obsessed with two creatures: Jabtars and One-Eye Dragons.
Jabtars are like gorillas but with spikes all over them (all black but with a greenish glow). Jabtars range in height from about 15 to 50 feet tall, depending on Seimi's mood and what objects are nearby for relative scale.
One-Eye Dragons are consistently much bigger than mountains. They are born with three eyes, but as they grow up, they lose their two baby eyes and just keep their one adult eye. [Note: Seimi dislikes being asked if young One-Eye Dragons tuck their lost baby eyes under their pillows for the Eye Fairy.] One-Eye Dragons can eat Mount Rainier, so that gives you a sense of scale. One-Eye Dragons can fly and can be ridden by those who know how to ride dragons.
Naturally, Seimi is an expert tamer and handler for both types of creatures.
