Skarros was a sorcerer who took over the Circus of Dreams in Gallantaria and replaced all its performers with Mandrakes.[1]
Nothing more is known of Skarros or of his (or her) involvement with the Mandrakes. It is perhaps possible that the smiling female clown who led the Circus of Dreams was in fact Skarros (or vice versa), but there is no evidence either way, and it begs the question as to why Skarros was referred to as a "sorcerer" and not as a "sorceress".
