For one of the few times in Grim's entire existence, he had a stroke of good luck.

A tongue of fire wrapped around Eris's leg, flinging her into the air and slamming her through the ceiling.

"Dad?" Grim gaped, staring at Hades, who had apparently hit another second wind.

"Eris is my problem too," Hades replied through grit teeth, "I've got your back, Grimslay."

"So do I, dude," Artemis murmured, shifting into his wolf form, "If you're going down, I'm going with you."

Grim spat out a clump of blood. "You have so much faith in me."

"What's the plan?" Hades whispered, watching Eris rise from a pile of rubble.

"I need her to sit still."

"Are you going to attempt to seal her again?"

"Something like that."

Another burst of wind ripped through the air, flinging Grim into the wall. Above him, the wall began to crumble. Hairline cracks spread across the ceiling, and Grim got another idea.

He threw himself into the brawl with Eris, back to back with Hades. Artemis darted in and out of the melee, sinking his teeth into Eris any chance he got. It was a fast-paced maelstrom of combat, the bloody chaos that Eris seemed to thrive on.

Grim plunged a tentacle into Eris's chest, tightening it into a writhing coil around his torso. She struggled as Grim slammed her into the wall, the foundation groaning with strain. Dust fell from the ceiling.

He struck with his remaining tentacles, sinking them into the stone blocks and grazing Eris's cheeks. She stared at him with wide eyes, sweat on her brow.

"You missed," she called, spitting out blood.

Grim smiled, giving her the very smirk that she was once wearing.

The hairline cracks turned to fissures, and the wall began to tremor. Eris twisted and squirmed, trying to escape from Grim's constricting grip.

The throne room collapsed.
