You were akin to beast-fey and beast-bonds as a child, able to understand and know animals better than people in only moments. This evolved, with your fey magic and history, and your ascent into ranger magic.

You became what's known as a Warg- able to understand animals in a soul-deep level, and to see through their eyes- 
And then to inhabit them. 

For a number of minutes equal to your ranger level, and for 3 times per day, you can inhabit the mind, eyes, and ears of an animal that is willing, or that fails your spell DC wisdom saving throw. You control, can see through, hear through the animals' body, and still retain your INT score, and can understand everything you normally would. 
This effect ends by will, when the time ends, or if the animal is killed. 

While warging, your original body is entirely helpless and senseless- you cannot hear or see, but you can speak.

If the animal is killed the warging creature takes 1d8 psychic damage per ranger level.
