The Smurfs found a mysterious code inside Gargamel’s spellbook. what could it mean?

So the Smurfs broke into Gargamel’s hut (again…) and found something weird tucked inside his old spellbook.

Not a spell. Not a potion recipe. Just a folded map… with a string of numbers scribbled on the edges.

And the same exact code was written in the margins of the spellbook too:

6•15•7•7•18•15•22•5, 3•8•1•14•20•5•18•5•12•12•5, 22•9•12•12•1•7•5.

They brought it back to the village thinking it might be some big plan of Gargamel’s to find their village, but the numbers don’t match anything they know.

Some Smurfs think it’s a place. Some think it’s a name. Some think Gargamel was researching something older than their village.

What do you think this code is supposed to point to?
