The Lurker appears in front of the Inn in Sunset Haven, but only at night. After a new homeworld has been chosen he will move to that colony. He offers to sell you rare goods and some exclusive familiars. A window opens up and you can buy (not sell) certain items. These can be useful, but they are sold at highly inflated prices (about 3 times normal prices), so be sure about any transactions.
