Of the options available to us, Incarnation is actually the worst. I realize that people are taken with the idea of getting together with the Yuhwaist witches, but this continual reliance on the authority of the dead does nothing but strangle the living. It sets us up for stagnation and oppression. Why should a person's leadership be sanctified by worship of a corpse? Are we so unable to act in accordance with principles that we must instead live the lives of those whose time has passed? Incarnation does nothing but play into Santsarran's self-strengthening propaganda and hand him a decisive card to play in the coming struggle over power and from whom it should be derived.
Disavowal is the ideal choice for building a structure of power founded on mass representation, but literally anything but Incarnation would better serve the needs of the people. Don't vote for the option that'll keep us stuck in the past forever.
