Too bad. Does Wizard Guy seem to have any conclusions about what happened or is she going to have to go investigate on her own?

He is flipping through his texts with increasing nervousness as another muffled boom resounds through the vault. So it looks like she's on her own.

If she exits the room containing the approximately wish-granting artifact, Velra will find herself in a large gathering hall, still made of metal but with a vaulted ceiling and painted devotional images on the wall. The center holds two columns of long pews, facing the door she exited from and a speaker's podium. At the far side of the room, she can see that there are stairs leading downwards, and two corridors that split off to either side. The explosions sound like they're coming from down the stairs direction.

Yup, makes sense that Wizard Guy is from a place that involves Wizard Lectures. Down the stairs she goes.

She gets the sense, as she descends, that 'down the stairs' is not a usual direction people here go. Not that anything is dirty, really, the opposite, if anything. There are no little wear patterns on the steps, no streaks on the fixtures from incidental brushes as people go by.

At the bottom, she finds a door that would look more at home in a bank than a wizard's tower. Beyond the door, she hears another explosion, sounding closer this time, and the faint clank of metal in fierce battle.

There's a wheel on the door she could spin to open it, if she wanted to.

She wants to. What's on the other side of it?

On the other side is what looks like a killing room. Wide at her side and narrow on the other, forcing anyone coming through the other direction into a choke point. Spiky protuberances and uneven dips dot the floor, not enough to provide cover but enough to interrupt the movement of anyone trying to cross.

To her left and right, Velra can see emerging from the walls a multitude of sleek silvery metal barrels, narrow and open on the facing end, mounted in turrets that allow their aim to traverse the arc of the room.

The sound of fighting is much louder here. It may be just one more room away.

She'll run right through it, slowing down only as necessary to avoid tripping, she's going to join the fight and there's no reason to let it go on without her. Hopefully there'll be some indicator of which side of it she wants to be on.

Well, on the one side there are metal creatures and static weapons emplacements that are defending the place she's coming out of. On the other, there are people in armor that is almost but not quite like full plate supported by more metal creatures. The weapon of choice for both is some sort of small wand-type implement that fires bolts of searing light, which flare back and forth across the battlefield.
