The first of the two dungeons the Prologue / Surface Stratum has to offer is something I feel I had in me since a long time ago.
I guess Blood Mansion should be considered a dungeon too, but I'm talking classic adventure-y dungeons this time.

Lake Goddess Shrine is an optional dungeon you won't need to complete in order to progress in the story, but I'm making sure to put a lot of nice treasures and events in there to make it well worth a visit!
Than, and the crazy Ferry Granny I love so much.

There's platforming, puzzles and a fresh boss battle waiting inside.
Enemies are sparse, but is a shrine that people usually visit near End City, I'd rather have it rely on puzzles heavily!
