Inferna

Backstory
 Inferna was the next in line for her people's leadership, succeeding her father should he fall or be unable to lead. Born with a condition that made her scales ingrown, she lacked the fire resistance most of her people had, and outright required protection from the arid heat the Embermaws lived in, something she was thankfully able to find due to her father's connections. After she was of age, she gained the Primarch ability to take on a smaller, humanoid form. To her astonishment, it actually hurt less than her true form. And so, she spent a lot of time in it, albeit feeling dissatisfied, in order to at least be able to move around more freely.

  The chronic pain resulting from her condition, however, paled in comparison to the looks and judgement she received from her peers. They were convinced the only reason her father valued her was because the clutch of eggs her mother had laid had mostly resulted in eggs that didn't hatch, or an even worse version of Inferna's condition resulting in them dying the moment they did hatch. In their eyes, she was a successor only by default, not by her merits or her potential, and due to her condition wouldn't be in any condition to lead them anyway if she couldn't stand at her full glory. 

  She knew exactly what they were saying, even if they didn't realize she knew. Her smaller stature allowed her to move about their camp with surprising ease.

Current Story
After years of living as a pariah in all but position, and her father's time running short from sheer old age, she had met a friendly face. One that she hadn't seen in a long time, since the first mentions of a demon attack. But he was very different. More outspoken, more devious... more powerful. And with that power, he offered her something grand. A magical cudgel, with a very complex enchantment placed upon it. When she laid hands upon it, she felt... nothing. The passive sting of her wounds seemed to fade. She even noticed the cracks in her scales healing over. To her shock, simply holding it seemed to heal her condition. But the man spoke again. Not only would remaining close to this cudgel remedy her condition's pain and physical affectation, but she would be able to take on other forms to a certain extent. However, he then presented two facts that made Inferna consider this gift carefully.

  If she accepted it, not only would she be required to lend him her people's service when her time as Primarch came, but her body's form would be at the mercy of the cudgel; If the wooden core of it shattered, then she would be stuck in whatever form she's in unless he was able to grant her a new one.

  It took her a couple minutes of deliberation. Her father's teachings were fresh in her mind... but they were drowned out by the quiet jeerings and mockery of the people she'd be effectively conscripting into whatever this man had in mind.

  The decision got a lot easier after that.
