Lex teleported over to the location where someone was knocking on his boundary wall, and looked over. An animal of some kind, similar to a squirrel with transparent wings on its back was smashing some unknown object on the wall.
For a moment Lex was confused. He could not tell if it was just a random animal trying to crack open some massive nut, or was actually knocking. Since the animal was technically outside his territory, he couldn't even scan it.
There was an easy way to find out. With a flock of his hand, the portion of the wall he was on turned into an equally massive gate, which began to swing open.
The creature was immediately startled and ran away before the gate could reveal even a speck of the land behind it, but Lex did not stop the gate from opening. He watched as it scurried through the tall grass and hid behind an old, dying tree.
