The Dark Summon

"What are these runes for?" 

The attendant glanced at them oddly, "Are you passer bys?"

Aesther nodded.

"Sigh… well, once you channel your mana through them, the runes can hide your soul aura entirely. The ghouls will not notice and they won't come after you."

A surprising light flickered through her eyes.

But before she could think further, the man grimaced.

"No, it's not so easy to escape from them," he shook his head again, "The rune can only for eight hours. You need to pick your time carefully."

"It's still good enough," Aesther thoughtfully added, "How has the city been holding on? We… uh… don't know a lot because we were stuck in a portal."

The ghost groaned under his breath.

"...long story," he said as they turned around an alley, "But I can tell you some of it before we reach Lord Ezra."

Aesther smiled a little in gratitude.
