Additional rewards/activities

Should a player look through the telescope again after the quest is completed, they will see the Scorpio constellation. The Observatory professor will suggest going to see his assistant. Upon speaking to the assistant, who reveals that his name is Patrick, he'll thank you for having made his life easier and give you a jug of wine.

He also mentions a book on the nearby table named Astronomy book, which speaks of Scorpius' grave. Travel past the abandoned buildings, and keep going north until you see some level 28 ghosts near the entrance of the Ourania runecrafting altar. The Spirit of Scorpius is located in this area with the ghosts; after a brief conversation, it will give you an unholy mould and tell you to return when you are worthy. With the mould, a ball of wool and a silver bar, make an unpowered symbol and return to the grave so that Scorpius can bless it into an unholy symbol.
