Monster

A monster, also known as a monster girl, is a human that has been transformed into another form by the magical powers of Velshara. Velshara is known to transform mortals into monsters as a "gift" to mortality, but she occasionally employs human collaborators that remain human but swear loyalty to her cause.

Transformation
Normally, when a human is transformed, their new form is determined by their environment. For example, a girl transformed in a forest may become a Mushroom or a Dryad, while one that transforms near the water may become an Octo-girl. The only exception to this is the monsters present in the Grand Cauldron, which always transform their victims into the same type of monster as them.

Traits
Monsters gain abilities based on the type of transformation they undergo, gaining special biological or magical skills as part of the process. Regardless of the powers gained, however, the personality of the newly formed monster will always shift so that the monster is unfailingly loyal to Velshara and dedicated to debauchery and transforming any human they encounter. Monsters are also immortal, and do not age with time.
