It's easy to understand
How you could fall so hard
-Reba McEntyre

Heaven is the more serious of the two nymphs, though she's not very serious at all. She loves to get her pleasure, but she tends to think things through a bit more than Lydalia does. Her pool of water is closer to the meadow than Lydalia's is, so she has met a few more people than Lydalia

Lydalia is obviously the more flighty of the two nymphs and so her sister ends up being a little protective of her. Pleasure is all she's after and how she gets it doesn't matter nearly as much as getting it. Both of the nymphs are great fun to have water wars with, though.

I see them so excellently fair,
I see, not feel, how beautiful they are.
-Samuel Taylor Coleridge
