Earendael’s Stitch Hound

Once upon a time a Noble family birthed a precautionary heir to their knowledge and wealth, this child grew up in harsh conditions, being the “back-up” child. As he grew older, he eventually began his studies in his family’s traditional (yet secretive) magics, and the lonely child studied hard, he had to in order to stand out at all among his two elder siblings. So, as he was friendless, he decided to make his own friend, thus the Stitch Hound was ‘born’. Needless to say, his parents weren’t impressed.

Over the course of an hour, you use a combination of magic, science, and alchemy to create a loyal, yet repulsive, abomination in the eyes of all that live. For the next 24 hours you have an undead bloodhound as a companion, after the time is up the corpse finally degrades into complete disrepair due to the acidic compounds flowing through its withered veins, the same corpse can never be used for this, nor any other necromancy spell used to reanimate a corpse.
