The Wilds Await
These are openings, partings or ebbs and flows of the Myst that is the main feature of the Mystbound Realms. Myst-tides can be regular, like the tides of the sea and cycle every day, every week, month, year for the same period of time. But irregular Myst-tides are also known that cycle once in a century or that recede or open and then permanently stay that way.
One type of Myst-tide forms a corridor through the Mysts and temporarily connects different worlds together. Some worlds are connected to many others by Myst-tides; others are completely isolated. The effect of such a connection is determined by how often, how regularly and for how long they open. If they open often and regularly, trade between worlds occurs. If there is any danger associated with walking a Myst-tide then few beings will hazard such a journey save at great need.
