Remora demon

 is a demonic species able to grow to fit wherever they might be contained, only kept from expanding by water pressure. Their appearance is comparable to an eel with an human-like eye. Remora demons were also known for eating lead and turn it into gold.

History
A Watcher in the Middle Ages was able to fund the Watchers Council using a remora demon to produce gold. This event started the rumors responsible for alchemists trying to recreate the process of turning lead into gold as well.

In 2006, the demon smuggler Sean kept a remora inside an aquarium. Athena Jamison-Smythe broke its glass in order to use the demon to fill a recently opened Hellmouth in the office, successfully closing it, while crushing the Silvera family to death.

Behind the scenes
