Sleeping Dragon this world was built on blood and battles (just like you)

Storm, as he had come to think of himself, heard the cry on the air. Heda’s voice thrilled through him and he caught her sound waves with highly-cupped ears. He felt an urge to answer the call, but the only way he knew he could was to echo it from his cave against the mountain, which he had come to call home. He had never before had a home, he had only ever travelled continually. The thought of belonging somewhere (even as Omega) was slowly brainwashing him into feeling that this must be all he could amount to.
 
They had no need for a cripple amongst their meeting. Perhaps one day, when he was not crippled, he could help Heda. For now Storm hobbled to the edge of his cave and lifted his long, thin muzzle to the sky to reply to her summons with a light, baying howl.

Whether or not Heda left a guard, he would not budge. Storm wished to serve her as promised in exchange for his life; if she wished he stay in his cave, that is what he would do.
