The Pook

The Pook is a shape-changer. He appears in whatever guise he thinks will be most confusing to you, depending on his purpose. He weaves spells to bemuse our senses and confuse our judgment. He is a master of the arts of illusion and delusion, holding up a distorting mirror to reveal the bad in the good and the good in the bad. This may confuse us further or it may help us gain a more balanced understanding of how things really are.

He is very against rigid mind-sets and, in his own way, encourages the development of inquiring minds
