The Clawed King

A story of a failed lich turned boneclaw bound to a pair of twin orphans who were sold into slaves by their adoptive aunt and uncle. When a mage of the order attempted to seek lichdom, he failed due to his frail body, and his flying spirit bound itself to the twins as a pair, splitting his soul into two. One boneclaw was filled with revenge, and seeks past grievances on behalf of the unknowing girl, whilst contempt and fear bound to the boy, seeking individuals whose spirits are similar to those who the children hate or fear. This split of past and present binds the children unwittingly to the fate of thousands in the surrounding town. A further complication, the children are drow and live in a conquered city razed by the hordes of the primary drow and later cruelly overseen by the second rights, meaning their hatred stretches over a great number of people.
To save this town, either the boneclaws must be slain, the children slain, or the children turned away from the path of hatred and evil. If left unchecked, the boneclaws would surely destroy the entire settlement and leader to division within the drow kingdom, removing any guarentee in assistance with dealing with the elven mage threatening ruin on the world.
