Tree dragons are very small beasts with very little magic. Generally they don’t get bigger than a household cat. However, due to the relative size of their heads they spend a large part of their time hanging upside down from trees because otherwise their necks get tired if they stand up.
Despite their size tree dragons are extremely strong and are known to attack and kill creatures over ten times their weight.
