Thanks, @GLaDOS.
Thulium, (69 Tm) is the second least common lanthanide, with the radioactive promethium being rarer. Thulium is important because it plays a role in the creation of the popular Holmium-Chromium-Thulium Triple-Doped Yttrium Aluminum Garnet Laser (Ho:Cr:Tm:YAG) as a doping agent. What this means is that thulium is added in small amounts to the YAG as an impurity to increase efficiency. Other than that, thulium is used in radiation sources and superconductors.

About Calla Eggs

This egg is, surprisingly, soft to the touch and resembles the texture of a horse's mane. Weird... it's actually... hairy? And occasionally, these eggs will fly away due to their wings. Keep this egg locked down tight if you want it to be hatched in your possession, as the creature inside is only loyal to the first human it lays its eyes on!

About the Calla Creature

Calla are a majestic cross between an eagle and a horse. It's able to soar high to dangerous elevations; elevations where humans would normally die due to the scarcity of oxygen. Not only can it fly and transport humans by air from its eagle heritage, but it packs an extremely dangerous punch with its back hooves if an attack occurred. Calla are loyal only to the first human it lays its sight on.
