After re-reading more carefully, I don't think my concept can work. I said "elder god" but I was actually hoping to play one of the puny plain gods that somhow survived the purge in a weakened state and wanders around helping others albeit with her own motives(worship, owed favors, and connections, etc).
Name: Caldra
Age:Unknown
Status: weakened fire goddess
Appearance: Especially at the beginning of the story, I imagine her as a hunched, hobbling elderly woman of grays and blacks in hair and clothing. Covered in soot and ash, her clothing all singed about the edges yet suitably thick for homelessness in winter. In her crone from, she dresses this way no matter the clime and seems drawn to almost any and every source of flame and when possible, will pause to hold her face or hands to it for warmth. She also is known to keep some sort of container of alcohol nearby which with her decrepit and hobbling manner, might lead some to think her a drunk. Actually she keeps it, as one might guess, for its flammability.
As she absorbs intense heat, she is recharged and may begin to take on a more glamorous and youthful appearance befitting her former station, appearing as a redheaded goddess whose skin may be pale or swarthy depending on her mood and power expenditure. Even if she chooses not to revert to her original form, she still begins to seem more colorful and spry even as a crone.
Sexuality: To her, heat is heat. She does seem to get strangely worked up when experiencing a significant charge from fire magic or the fear/awe/adoration of mortals though.
Skills: She can shapeshift into a small assortment of generic human forms but can not imitate anyone specifically. As a "crippled" fire deity, she has an immunity to fire and actually experiences temporary revitalization effect from human reverence and extreme sources of heat, especially ones she did not create herself. She has a limited ability to cast fire spells and teleport between multiple flames in close proximity to each other but the former quickly depletes her power stores and leaves her that much closer to actually being little more than a fireproof old homeless woman. She also possesses durability and strength belying her frail appearance.
Other:When the immortals mutinied, Caldra met her would be assassins with the full brunt of her explosive temper. And though she knew she could never permanently kill them, she derived a certain sadistic glee from punishing their insolence with scaldings and immolations. She temporarily cremated waves and waves of immortals before they finally overtook her. Defiant to the very end, she triggered an explosion but miraculously found herself millions of miles away, alive but in a body afflicted with weakness such as she'd never known. After re-orienting herself, she began to wnder the Earth, semi-incognito(she plays a risky game of revealing herself to some so that she might feed on their fear and adoration while trying to duck the attention of immortals who might want to finish the job), but now she senses the coming of a worse threat. She may need to resort to the help of even former enemies if possible.
OOC: That's sort of off the cuff the concept I had. Her powers might seem OP, but I think of character powers less in terms of points and more in terms of theme and story. I see her as sort of a helpful-witch-with-suspect-motives archetype.
I imagine her pretending to be a strange old lady with fire magic some of the time and blowing her cover to have petty power trips that get her into trouble the other half.
But I realize now that it would have to contradict the idea that all the non-EG gods to be dead. Maybe a tweak is possible? But I wouldn't worry about it too much. If the character just can't work, that's fine with me too.
