A goblin is a legendary evil or mischievous grotesque dwarf-like daemon or monster that appeared in European stories and accounts during the Middle Ages. They are ascribed various (sometimes conflicting) abilities, temperaments and appearances depending on the story and country of origin. In some cases, goblins are little creatures related to the brownie and gnome. They are usually small, sometimes only a few inches tall, sometimes the size of a dwarf, and have magical abilities; they are greedy, especially for gold and jewelry.
Goblerna takes on the image of goblins often used in RPGs who are fought in the near-beginning of the game and pose little to no threat to the player.
