Curtain

undefined:

Curtains are memory or communication barriers that are based on location in a system rathern than around headmates or groups of headmates. Anyone passing through a curtain may have to leave some memories behind, and communication may not be possible through a curtain. Curtains can be lowered over time similarly to other kinds of barriers.
