Dragons on Altris come in a wide variety, some are extremely rare and are seldom seen. Not all dragons on this world however were created equal, some, even though appear to be the same in another land, can be either far more powerful or extremely weak.
On Altris dragons are broken up into four types; metals, chromatic, environmental and other. Some scholars on the world are attempting to group the gem type dragons with the metals calling them “mineral dragons”, this so far has not caught on, and has been met with heavy resistance.
