Tyrael perks up a bit at this. "You rescued her? Truly?"

Li-Ming rolls her eyes. "Yes, Tyrael. Good job, Felix, I knew we could count on you."

"Yes, my friend," Felix says patting him on the back. "Now we need to kick demon ass."

They arrive at the Silver Spire. It doesn't look particularly silvery; it's been corrupted and befouled by demonic magics. It's covered in disturbingly organic growths and black detritus.

Tyrael stares. "I thought I would be happy to see my home again after all that has happened. But this..." He shakes his head. "Diablo must pay for this."

"Don't worry, dude. Revenge shall be yours."

"Yes, but let's not get distracted with dramatic proclamations."

"Agreed."

Upon entering, they may notice that the spire is packed to the fucking brim with demons. There's a strange device on the other side of the room.

Tyrael points at it. "That's the teleporter to the upper level."

Li-Ming sighs and starts blasting demons.

Sigh indeed. Demons can meet the other end of various magical implements of combat.

They eventually reach the teleporter and are transported up.

The floor they end up on is covered in drifts of snow and ice. There are several angels fighting a hulking demon, who toys with them like a cat with mice.

The demon notices Tyrael, and with a swipe of his sword, he dispatches the angels. "Tyrael! It seems we've both fallen from grace now. Come, embrace your former lieutenant! Or do you not recognize your old friend Izual?"

Tyrael grits his teeth. "I failed you once, old friend, but today I will put you down as I should have years ago."

The demon grins gruesomely and charges.

In absence of a nipple ring to aim at, Thomas will just throw hunks of rock at the demon's face to blind it.

Izual roars with rage. Tyrael takes advantage of the distraction to slash at him with El'Druin, but the demon blocks his attack with his own sword.

Lorath makes a pass with his staff, and Izual lights up with a sickly blue glow. His movements slow for a moment, and Tyrael scores a hit with his blade. Then the demon shakes his head and the blue glow recedes. He opens his mouth and releases a blast of ice which freezes Tyrael in place, then smashes a fist into the ex-angel's chest and breaks him out of the ice.

Tyrael goes down and doesn't get back up.

Fernando flies and checks on Tyrael.

Well, he's breathing. It's labored and clearly painful, but he is breathing.

Li-Ming is blasting fire at the demon, who is... laughing at her. Once she observes this, she switches to bolts of arcane force, at which he does not laugh.

Fernando will try to coax Tyrael into drinking a healing potion. If that fails he will just drink some himself and then transfer health into Tyrael by sorcery.

Tyrael is capable of swallowing the healing potion. He gasps as his broken ribs set, then gets up and staggers in Izual's direction.

Li-Ming manages to stun the demon with an arcane blast, then fire a concentrated ray of purple light through his left wing. As he screams in pain, Tyrael punches his holy blade directly through his heart.

The demon slumps to the ground. Tyrael wipes the blue blood off his sword on a nearby snowdrift wordlessly.

Felix will pat him on the back. He actually manages to make it not-awkward. "Do you need a moment?"

"No," Tyrael growls. "I need to kill Diablo."

"Amen," Li-Ming says, walking over to the next teleporter.

"Praise be sweet revenge."

Up the teleport they go.

The angel who was yelling at Tyrael before stands in the room above, holding a great flaming spear. "Nephalem! You wrought this destruction, and now you violate the sanctity of Heaven itself?! I will strike you down!"

"Oh come on," Li-Ming groans. "You're seriously going to attack me for trying to fix a mess I didn't even cause? This is the last time I help an angel."

Abruptly, the tendrils of light making up the angel's wings flicker and die out. He collapses to the floor, screaming in agony. "The- the Arch! Diablo- agh!"

Lorath shrugs. "Gee, what a surprise. Maybe you should've been focusing on him."

"No offense, Tyrael, why so many angels are crazy?"

Tyrael sighs heavily. "Imperius has always been... distractible. But we must hurry! If Diablo succeeds in corrupting the Crystal Arch, all is lost!"

There's a gate leading into the Chamber of the Crystal Arch behind Imperius' unconscious body. Tyrael smashes it open with El'Druin and gestures for everyone to go through. "I spent too much of my energy fighting against Izual. You must do this yourselves."

Lorath makes sure to step on Imperius as he proceeds.

The triplets restrain themselves to just give the angel a judgmental glance.

(Thomas figures he can take a selfie after the battle.)

The Chamber of the Crystal Arch is even more glorious than the rest of Heaven. The Arch itself has Diablo perched atop it like a very large bird, blackness spreading from where she touches it. 

"The Seven Evils are one within me," she roars. "I am unstoppable!"

"We'll see," Li-Ming says. 

Okay, so using his density sense Thomas can tell that Diablo is about twenty times denser than a human, given distance and air resistance... okay. He has a plan.

He will throws a large rock at Diablo!

The rock crumbles to gravel as it impacts her skin, to no visible effect.

Diablo hops down off the Arch and takes a leisurely walk towards the party. Li-Ming begins blasting her with arcane force, pitting and scarring her rocklike skin but not penetrating past the outer layer.
