Tower of Druaga is full of mysteries. I am a bit intrigued, but god help the creators if they use them for sequels. This time we learn a little bit about the mysterious duo of ghosts (I call the blue one H1 and the tan one H2), but not too much. H1 always was cold. H2 talks about waiting for special someone and informs Jil about Neeba getting into a pinch. So I'd say they are something like opposite halves of Ishtar.

Dunno if this is significant, but here's the list of people who recognized the end of the summer: Gilgamesh (duh), Ahmey (!), Parsuz, Kelb, Neeba, and... Kaaya. Oh yes, she sure has an agenda, check out this face:

Regretfuly, Druaga suffers from the generic face syndrome. I only distinguish H2 and Kaaya because of the ghost glow that surrounds H2. On the other hand, Kaaya has awakened H2, so maybe it's all right.
