In the RPG
This small, skipping creature looks a bit like a thin, gangly, orange goblin. Large ears spread from its bald head. Its pupil-less yellow eyes stare as it raises a clawed paw. Grell are small, playful creatures that can be encountered in wild areas. They are not particularly dangerous individually, but in gangs they can pose a threat to outlying night elf and furbolg communities; they may be small and unimpressive, but their claws are sharp. Scattered groups of them are actively malicious. Some grell wear earrings, which scholars believe may possess magical traits. Grell are fond of hyacinth mushrooms. Combat Grell are not particularly hostile; generally, they are content to leave potential dangers alone. If an opponent attacks, however, they defend themselves fiercely. Grell in a gang feel no particular connection to each other, it seems, and are as likely to assist their comrade as to watch the combat idly.
