The Forest Queen instantly recognized the advantages and disadvantages of the Tree Spirit People. Her words were not only meant for the Tree Spirits but also meant to awaken Gaven and the others, reminding them not to recklessly rely on the Tree Spirits' ability to automatically revive through symbiosis with the Treants to undertake dangerous actions.
"Thank you, Your Majesty, for enlightening us. However, Your Majesty should not forget that the Tree Spirits are deeply sentimental beings. Even towards life forms they've briefly been in contact with, they form strong attachments. Let alone with the trees they have shared a longstanding symbiosis."
Most Tree Spirits would rather face death alongside their symbiotic trees than choose to use the Symbiotic Transfer Ritual.
