Holy Places - All of the Deru holy places are sacred trees. Trees of a very large size, exceptional beauty, or with unique physical or other characteristics can indicate a tree is sacred. These things however are just a clue to the power of the tree's spirit. The decision to make a tree sacred is ultimately decided by the council. Only a seasoned and powerful Deru, one that is in perfect balance with nature, can see the sacred aura of a tree.
