About The System

We don't know the exact terminology for everything, but we are a plural system, hosted by Sylvia. Hence, the name. Sylvia is also nearly always co-fronting with another headmate, with the exact ratio of who is controlling "how much" varying and fluctuating.

Here is a list of the members of the SylSys, in alphabetical order.
