[@Ashevelendar], while any being or beast that originates from humans is "fair game", the majority outside the list you see available in the information sections are considered mostly unplayable. For example, a ghoul or zombie might be a creature one would encounter, but the issue lies in their unsuitability for play by a participant.

While I do not outright rule anything out beyond that, any submission outside the standard guidelines will receive added review and calibration. From experience and intent, monsters do not make "good characters"; they are meant to be, in this story, a significant issue for both themselves and their companions - the other players.

All the same, if you are set upon creating something unusual, please refer to the "standard" options to understand my operations.
