Astrafractal
Astra (relating to stars, or a cosmic sense of infinity) and fractal (infinite, or an infinitely recursive pattern in chaos theory.)
This refers to systems who are vast in size. This can be used by systems regardless of their origin. Systems who are astrafractal have large systems. They have many hundreds or thousands of alters. They often don't have an exact system member count and may feel effectively or literally infinite. They have a complex system structure. May feel like their system, or parts of it, is an entire universe or city. They often face stigma from others, even from other multiples who even may consider themselves polyfragmented, who disbelieve systems can be that large or splitting can be so frequent.
The purple gradient represents all system origin types. The azure strip represents large systems with hundreds or thousands of alters. The rainbow gradient represents the infinite wonder of consciousness. The chartreuse stripe represents complex system structures. The orange gradient represents love and acceptance for the whole system, no matter how unconventional they may feel next to other systems. The black stars represent all alters in a system, including unknown and uncounted ones. The smaller rainbow stars and the fractal represent the infinitely complex and beautiful nature of the system.
