Zoroark got away quickly enough, and tried to turn invisible in
order to escape from any battles that he might get into, but
realized that he couldn't use Illusion. "What in the-?!"
(They were fighting on the northern island, outside of the
Unown/Aron/Yveltal caves, unless I misunderstood you.)
Zygarde noticed that he had accidentally started a small
earthquake, and quickly put less energy into the Land's Wrath,
which was only being used to make the earth glow. "Sorry!"
(OH! Sorry; I somehow misread that as "Yveltal was on the Northern
Island, after leaving the underground tunnels." XD)
Zoroark was looking around for a safe place to stay, and found a
cave near the base of a mountain. Hoping that nobody was occupying
it, he went inside and quickly ran towards the deepest parts.
Okay! he agreed before Teleporting all three of them into
the cave. Unaware of the Zoroark hiding in the deepest parts,
Gardevoir laid down on his bed, happy with how the day went...
