Lady Guinevere and Lady Cordelia belong to two of the oldest and most noble families in Faeo, the only families that know the secret of taming spirits. They have the ability to transform incorporeal spirits, released from mortal bodies, into ghostly forms and wraiths. For doing so they need essences of living creatures and they need the help of your clan to get these essences.
Warriors who have a pet may obtain these pet essences in battles with monsters of their own level. In order to be able to see these essences they need an Elixir of Ghostly Vision
which can be obtained from Guinevere
The ladies are not asking individual warriors to obtain these essences, but whole clans, as they need a huge amount of them and they are too busy to talk to every warrior. Clan leaders can exchange the essences which their clan members obtain for Sprit Charmer Reputation
for their clans. If a clan has sufficient reputation they can obtain a special Clan Totem
and the more reputation you have, the more powerful will your totem be.
Here you can find more information about the Spirit Charmers.
In order to receive Pet Essences warriors from level 5 who are members of a clan need an Elixir of Ghostly Visions which can be obtained from Lady Guinevere in Frontiermarks or Lady Cordelia in the Domain of Winds. Clan leaders can hand in the essences and receive reputation which is need for getting a clan totem.
