The Collector first spoke to the elder.
"Tell me of the mechanics involved within ownership transferal regarding these lairs known as 'dungeons," said the Collector. "Specifically in regards to geographic proximity. What occurs when my physical presence exceeds the boundaries required for ownership?"
