Nearby refers to the current square and the eight squares that surround it (including diagonals). For example, the middle square has 9 nearby squares - itself and eight others. If a square is in the corner of the realm, it will have fewer nearby squares. For example, the bottom right square has only 4 nearby squares - itself and three others. When referring to nearby sites, nearby voids, or nearby squares the effect can cross the boundaries of regions. For example, Ultimate Horror can be in the void and still summon to a nearby site, even though sites and voids are in different regions. For all other references to nearby, such as nearby locations, nearby minions, nearby artifact, etc., regional boundaries must be respected and cannot be crossed. For example, if Belfry is on a site, it will not untap allies in a nearby void, because 'nearby ally' cannot cross a regional boundary.
