General Remarks about "Song of the Caverns" in the "Lytha Way"

I played this mission 3 times now (the first two attempts were to explore and to enjoy it). The third, was the attempt to play it in the "Lytha way". It worked, and I fear that it has no expecially tricky situations - use the secret passages wisely, and stay in the shadows whereever you can. But, it is a highly time-expensive adventure, because one is forced to crouch+walk slowly as good as all the time.

More Hints: to be written.
