Perhaps 'Abyssal Descendant' can be used as another name for tiefling in a story. Tieflings are often thought to have some sort of connection to the Abyss, a place of chaos and demons in many fictional universes. By calling them 'Abyssal Descendant', it not only implies their otherworldly origin but also adds an air of mystery and danger to the characters. This name can be useful when you want to create a more menacing or exotic image for the tieflings in your story.
Stealing or thievery could be used instead. For example, if you don't want to use the made - up word 'tiefing', you can simply say that a character in the story is involved in stealing. It's a more common and easily understood term.
The tiefling origin story is often rooted in the idea of a fiendish or infernal bloodline. They are typically descendants of humans who made pacts with devils or other powerful fiends in the distant past. This connection to the infernal gives them their distinct features like horns, tails, and strange eyes.
A Tiefling Warlock could have a back story like this: A young Tiefling was outcast from his community due to his fiendish heritage. While wandering alone in the wilderness, he stumbled upon an ancient, dark tome. As he opened it, a powerful, otherworldly entity made contact. This entity promised the Tiefling power in exchange for his loyalty. Desperate for a sense of purpose and power to overcome his outcast status, the Tiefling agreed and thus became a Warlock, with his newfound powers fueling his journey to prove himself and perhaps one day, return to his community on his own terms.
Food pilfering is also a good option. This implies that the character is secretly taking food, which is quite similar to tiefing in the context of food. It gives an idea that the act might be a bit underhanded.
A Tiefling Warlock could have a back story where he was an orphan. Left on the streets, he was taken in by a group of thieves. One day, while stealing from a wizard's tower, he found a strange amulet. When he put it on, he was contacted by a powerful entity from another plane. This entity was intrigued by the Tiefling's tenacity and offered him power. In return, the Tiefling had to use his newfound abilities to steal magical artifacts for the entity. So, he became a Warlock, using his powers to carry out these tasks while also trying to figure out a way to free himself from this deal.
The novel did not reveal his true identity in the work. Under normal circumstances, they would sign their names using stage names or pen names.
Using one's real name and signature could better protect one's identity and make it easier for others to recognize one. A stage name or pen name could better reflect and make it easier for people to remember the work.
Of course, the influence and audience of the work had to be taken into account when signing the name. If the work is well-known or has a wide audience, using your real name or stage name may not be the best choice. In this case, it would be easier to remember and spread a pen name or stage name.
