THIS SEEMS SO OBVIOUS HOW DID I NOT REALIZE IT SOONER. WISP = BIRDGIRL (they even explode violently in the same way when you die!), COLLECTING HER CATS. SOMETIMES LAVA (SCOPPIO) OR CROWS (MOJA) OR SPIKES (MELISSA) GET IN THE WAY THOUGH... BUT AT THE VERY END AFTER A HORRIBLE BATTLE WITH A GIANT DEFORMED DEATHBIRD WISP FINDS THE FINAL CAT, EINHAG.
