Nathan's Fourth Familiar (Bonus)

"We'll reinforce this area." Nathan explained to the two summoners and the rest of the fighters before Sera's voice echoed from the distance.

"Nathan. I'm done with the summoning circle."

"You should go. I'll handle the rest. The success of this defensive battle relies on you." Flora nodded. "The people have come back, so once you're done with the summoning, we can fight them."

"Alright!" Nathan dashed to Sera and checked the summoning circle. "Everything is good. I can proceed to the summoning."

"Yes." Sera glanced to the side. Anubis came to him, bringing the mulberry tree into the circle. "Everyone has been healed. This is the tree. Do you need anything else?"

"No." Nathan summoned Nidhogg. "I need your blood."

"Take as much as you need." Nidhogg understood their circumstances. If he was stingy, there was a chance the summoning would go wrong, so he just gave whatever Nathan wanted so that all of them could survive.
