Merlin's Magic Shop
After Arthur left, Merlin opened a small shop to keep life going on.
The first story is the "Magic Shop". It has tools and medicine. Those tools are not regular tools. They can help the tool keepers to finish the job more efficiently.
The second story is the kitchen. Merlin can prepare the medicine and the food here.
The third story is the bedroom. Merlin can read and write his journey here.
The clock on the clock tower ticked and ticked. Merlin stayed in his magic shop waiting Arthur to be reborn. Maybe Arthur will step in the shop and reunion with Merlin very soon.
