Above is an earlier strip in this particular tale of Inherit the Earth.
Summary of the current story so far:
Annabelle, Dolores and Cecelia have sneaked out of the Dog Castle to attend the annual market faire while Prince is away.
Annabelle is shopping at Kylas Honeyfoot's booth, when (unbeknownst to Annabelle and Dolores) Cecelia takes a ring.
While the three are traveling home, Cecelia (also known as "Sissy") starts to act very odd. She appears to be having a conversation with some invisible Morph.
Dolores finds it amusing, but Annabelle becomes alarmed when Sissy announces a desire to become chieftess of the Dog Tribe!
