"Nissa died channelling all the Green mana of
Zendikar into a snare that could hold Ulamog
and Kozilek. She held on to live just long enough
for Chadra to do her job of burning them. Liliana
was there, and could do naught but raise her as she
died, as she had with Gideon before. After all,
Emrakul was still free, somewhere."
