you'll have to actually purchase some Sense ability to use it in the future
The way I envisioned it working was he steps into a Ley Line and is able to ride it to a destination that is close to where he desires to go. He does have Eldritch Awareness which I figured would allow him to sense a major Nexus in close proximity, an "On Ramp" if you will. Being educated in the Arcane Arts, and Ley Lines not fluctuating much over the ages, I figured he would know where the major ones are and how they end. Similar to how a person who commutes everyday doesn't necessarily sense the highway, as much as he is familiar with it and the direction it runs.
"Ahh, the Americana Arcana ley line runs east-west, bisecting the Egyptian Eldritch stream at Stone Henge, then we can travel south along that until it bisects with the India Karmic stream about 500 miles north of Madagascar, where we can exit the nexus and make our way to our destination."
I had assumed that is typically how he would plan his 'Ride the Ley Line' trips, though I supposed I could have clarified that a bit more in the IC post if I had thought of it last night. But looking at it now, as he isn't able to perceive his destination, I should probably purchase Accurate for the teleport.
