All characters have an alignment, but not all characters have chosen one. No character needs to choose an alignment until after the reach 1st level. If you have not chosen an alignment, you are considered to be Neutral.
Archaic Alignments from MCC also exist in Ruined Toronto. Having an alignment does not preclude belonging to an Archaic Alignment. Belonging to an Archaic Alignmnet does not remove the requirement to choose an alignment.
Thus, Ruined Toronto can have Lawful, Neutral, and Chaotic plantients, and wizards who belong to the Clan of Cognition.
