He can establish his barriers quite quickly

“Depends on what’s hitting it and how often,” I said. “The whole thing would be about half as strong in theory, but…to be honest, I wouldn’t want to let an army of Grimm start wailing on it either way. The way Grandmother described it in her story, they used it to fend off the small Grimm while Hunters dealt with the larger ones. I can probably withstand the attacks of any small fry, but if something big gets at it…I don’t know. How well it can hold back an army isn’t really the type of thing I’ve gotten a chance to test. Until now, I guess.”

She took a slow breath and shook her head.

“Do what you think is best,” She said at last. “You’d know better than I would. We’ll try to keep the Grimm off the walls in any case, but…just in case, how long will it take you to put it back up if it falls?”

“Not too long,” I said, calculating. “Depends on which barriers I put up.”

I looked around, considering possible setups.

“I could split it,” I mused aloud. “Like a sports field, again. Have the hole on that side, with Sanctum and Safe Haven to lock them in and wear them down faster. Have Sanctum Sanctorum and Temple on this side giving us a benefit, healing, and helping me regain MP. If I set up now…”

“Please,” Isabelle said and I around to make sure everyone who was supposed to be here was. Ren had returned with Keppel and Carmine and Nora had come back with my mother’s group. With my father and Onyx coming up from the hole soon…I focused and felt invisible barriers rise into place around us.

Apparently, I wasn’t the only one.

“Isabelle, what’s going on?” A red-haired man I vaguely remembered asked, squinting around us.
