Stella posted final challenge of the week, this challenge require solving all last week challenges to solve this one.

We can see that this puzzle is consisting of five parts. Right  away occur to me that this must be related to last week puzzle.

Looking at the solution of the last week puzzles.

For first part we see the first number is 7, 1 , which mean seventh word and first letter , if we look at the first puzzle of the week solution we have word "Proving" so we take P and so on like this:

After getting all five part if we read from top to bottom by merging the letter we get  Prometheusthefirebringer which is the solution for this puzzle.

Then the code we got we put at the end of the Url: Stl.la

Like this: Stl.la/Prometheusthefirebringer
