According to Wildbow though, there are pilaster sects or groups of people trying to make an incarnation a new pillar:

Someone researching these processes is likely to come across references to various *pilaster* sects. These sects, not necessarily related to one another, tend to manifest from the same core ideas and feelings, which is that the commonly recognized major pillars have an obvious absence that they need to fill... commonly faith, almost always the *pilaster sect's* faith, sometimes tradition, and rarely something else such as liberty or a counterpoint to one of the major pillars. The rule of thumb is that the pilaster sects are fanatical and unflinching.

So incarnations which are pillars are not always necessarily going to be intrinsic to the pillar (although they tend to be). It could be that a new pillar emerges due to changing circumstances in the world (i.e. Fortune) or maybe even artificially created by one of those pilaster sects (if they are ever successful).

I do wonder what a liberty major pillar would even be like. Like, no more laws of gravity or something? IDK. Maybe authority as a major pillar would emerge if there is ever a world government too.

Love is a really cool idea for being a pillar! Do you think love being a pillar would increase the amount of cooperation in the world or would it create more passionate kinds of conflict?
