Her name is Pжавa.
I forgot to mention that Greenleaf is not cowed by Pжавa (rolled 23 Will save).
If Greenleaf uses Rapid Shot, she must use three arrows, because you have to use a full-attack action to use Rapid Shot.
One arrow bounces off Pжавa's soft underside, and the other misses completely (rolled 19, 7). Good thing Greenleaf did not aim for the hard scales around the rest of Pжавa. Greenleaf has 17 arrows left.
Round 556: Pжавa flies to 50N15E30Z, northbound. She appears unconcerned about Greenleaf's arrows.
