Divine Sanctuary should not be confused with Institutional edifices of the Followers (though such edifices can also be sanctuaries).
Holy Ground is land and/or a structure consecrated to the service of a faith or Divine Principal. It can be any location or structure (waterfall, church, etc.). The effects of Holy Ground depend on the level of consecration. Holy ground does not necessarily have any adverse affects on those of opposing faiths or tenets (unless part of the sanctification process); however its benefits are only afforded to followers of the same faith. All Holy Ground affects the ease in communing with a divine Principal.
These apply to those of the faithful Followers only.
Often times, holy places of a faith are infuse The Risen of that faith with power.
