Many people met at the farmlands to join the ritual which the High Druidess Nai would lead. The Call of Oak, Ash and Thorn is a prayer to Silvanus, wherein a priest gathers leaves of the three named sorts of trees, floats them on water, and entreats Silvanus to hear a prayer.
After Nai and the rangers from the Elder Circle had handed out the sacred leaves to everyone, they made their way to the Water Cave in the Thundars Ride. There the feral elven druidess began the ritual with her prayer to the Oak Father.
One after another placed the leaves to the source of the water that feeds the farmlands. Many prayers to the Oak Father and to many other deities were spoken before Nai asked the participants to leave. For to complete the Call of Oak, Ash and Thorn she had to speak to Silvanus all alone.

The High Ranger Vendor Xon lead the company back to the Farmlands where saplings waited for them. As they arrived he asked everyone to plant a tree. He told them that they have to take care for the sapling as they would grow to a great tree. They had to look for places that were tainted badly, speak a prayer, use a remove disease, a heal spell or a blessed potion to clean the soil, dig a hole and plant the tree.
So they divided into small groups, and all around the farmlands people where seen planting their tree. Prayers were spoken and some even gave names to their new fosterlings or sit by them for a while.
Than Nai returned with many seeds after she had finished the ritual. More Sowing in the fields was done, and the High Druidess planted her tree as well. After everything was fine she shifted into a water elemental and watered the young trees and the fields.
Nai and Vendor Xon thanked everyone for the help and told them that it was only a push to the land as nature will recover itself. Now it would be up to the farmers to cultivate the fields and begin the sowing for the incoming harvest.
