Sapiens here with a Ghost Sovereign Soul Weaver, since a ghost kingdom sounds exceptional with Elder Kingmaker.
Who would play your character in the film version?
Summer Glau as she was in Firefly, waifish and unnerving.
Why did you decide to submit this character?
Margarice was the name of a villain from a cherished campaign I mastered years ago, and I've been wanting to bring her back.
And I've long wanted to make a creepy character. Between "soft" necromancy (this class has ghostlike servants) and Alteration Sphere fleshwarping, she'll grow up to walk the fine line between the usual and the eldritch horror.
Give me a short character background
That a stray kid is placed on the stairs of a church is a known story. Less common is for an infant to be found in a graveyard; Margarice was found at winter's solstice, laying on a nameless grave in a Rostland cemetery, by a Priest of Pharasma who was investigating rumors of a ghost infestation. And as he found the spirits, he found the infant, sleeping on the cold marble, wisps and other ghostly presences lying around her.
Her childhood was hard: the Pharasmin refused to deal with a kid so shrouded in necromantic energy, and a traveling priestess of Desna took her in; when the priestess was burned at the stake as a witch, Margarice had to learn to fend for herself, hiding her budding powers, lest she ended up on the pyre as well. But soon enough, her necromantic magic slipped out of control, in a healing flash, a scornful assault, or an uncanny fleshwarping, and then she had to run away. Until she saw a charter for a fiefdom in the River Kingdoms: there she could make a place where she wouldn't be persecuted.
Is the character appropriate for the AP and story?
I believe so. She's high on Charisma and creepyness
Is the character well-rounded, and able to contribute in multiple facets of play (combat, diplomacy, etc)?
Yes, especially in a few levels. Soul Weavers have a lot of utility with the bound souls mechanics, if I could pick Rituals I'd add utility casting, and I have lovely Diplomacy and UMD.
Am I interested in seeing this character grow and develop?
You judge it. But she has room for growth, from the scared girl who was hunted as a witch to a proud landholder.
[b]Will this character work well with others I've selected?[b]
It will depend. She'll do some business with death, souls and alteration that could be seen unfavorably by a superstitious barbarian, a "suffer not a witch to live" paladin or a cleric of Pharasma. But generally, she can round up any team, adding support, buffs and debuffs, and if she could come to trust someone, it would be personal growth.
