Phel's Links
Phel was rather surprised his wish for companionship was actually granted - especially with such force into the ground. He was intimated, but eventually became enamored by Arbiter and loved talking to (or at) him about his books and study and continues to do so.
Arbiter literally fell from the sky into Phel's care. He didn't know a lot about life planetside so he often followed Phel around to learn. Eventually, he became fond of the other and despite the dull longing to return to the stars (and the good graces of his patron) he is content with life alongside Phel's quiet comfort.
