Dark Gloom is an extremely rare dragon that appears in bottomless valleys. It feeds in the dark on the carcasses of its prey and is every adventurer's worst nightmare. Thanks to the tireless efforts of the Osiran adventurers and the Laedis Academy, Dark Gloom's tricks were seen through, and several of those dragons have already been captured by the Laedis Academy.
Those were then trained to get along with other dragons and creatures of Auratia and are now being given to worthy Osirans who can provide them with a cosy home or action-filled battles.
