Slug

Slug is a mentioned dragon character created for the School of Dragons Website.

Having an Adventurous Rider
Slug is a Gronckle with a young Viking rider named Magna Heartaxe. Magna is bold and adventurous, and may 'volunteer' Slug for dangerous activities. One such is Magna's desire to fight and defeat the villain Nikora Stormheart. However, Magna's designs are thwarted after seeking information from an old man named Garth.

"I once thought that I could go against Nikora Stormheart with no one but my Gronckle, Slug. I believed that I was the strongest in my village, and that I could take her on alone. To prepare myself for the journey ahead, I went to the one man in my village who had ever fought her and survived, an old man named Garth. I thought that he would be proud that I, a young Viking, was brave enough to stand up to Stormheart, but what he had to say left me dumbfounded… “You’d do your best to just forget about Nikora Stormheart,” he said, taking a swig from his drink."
