What information do the Towers get from their markers? Could a marker ID Dehane in some way? that would argue for Dehane removing them.
How closely can a Tower pinpoint the location of a marker? How much location information do they store? Can Dehane be identified by where on the planet he goes?
So of he erases a marker would the Towers know? Probably. so the Towers would have a record of removal sites. If they start reoccurring in the same location, you have a possible lair site.
