This one was created for a specific purpose, a specific desert adventure. The gemstone equivalent came later, when I needed an extraplanar sage for the PC's to visit.

Yellow dragons are among the most dangerous predators on Mystara. They are, thankfully, confined to blighted and cursed lands such as volcanic wastes, the driest and hottest of deserts, and the cursed wastes North of the Savage Coast. They are typically ambush predators, hunting prey that passes by their cave lairs. They can lie in wait, buried in sand, for weeks waiting for prey to pass by.
The gemstone equivalent of the yellow dragon is the citrine dragon. Little is known of the citrines, they are rarely sighted in Mystara but they are known from some of the scorched inner islands of the plane of Eloysia and are quite common on many of the hotter Energy planes. They are gifted spellcasters, often having magic user and clerical spell casting ability far in excess of what is listed, and as a result they are often chosen to be the servitors and negotiators for Diamond, the immortal ruler of all Lawful dragons. They often act as sages, their vast lifespans allowing them to gather huge amounts of knowledge that they are willing to share with other good and lawful beings (for a tribute).
Both yellow and citrine dragons have as a breath weapon a ball of burning, sulphurous fire that explodes in a sphere when it hits a target. The citrine dragons breath weapon also causes a melt effect, identical to that of a ruby dragon.
