Darkfall Unholy Wars really requires PvP to function properly; it's one of the big elements of the game. That's why the new Relic system was introduced to help encourage inter-Clan warfare, provide more benefit to Clan holdings, and generally shake up the established order of things. Nine relics randomly spawn throughout the world, and players who find them can bring them back to their Clans' churches to receive a global buff as long as the church is standing.
Relics can also be destroyed by taking out the structure that holds them or via a special altar, both of which will cause the item to respawn at another random location throughout the game world. The intent is obviously to encourage players to go to war over the relics, stealing them from foes or ensuring that no one can benefit from their presence. Time will tell how successful the system is; take a gander at all the details if you're considering jumping in to hunt some relics yourself.
