She needs his help again.
Apparently glow-worms work differently to fireflies:http://www.otago.ac.nz/news/news/otago664460.html

Espen's personal Quest
The problem started a couple of months ago
Firefly Queen Cave 2
Another Firefly Queen is in the High Forest, south of Noanar’s Hold
There are stakes surrounding her cave that channel the magic from her.
The queen inside the cave is near death.
If the characters pull out any of the pylons, they hear a horrible screaming, ripping and tearing sound coming from the east.
Smells like brimstone
Looks like a huge anus wreathed in flame and smoke.
It widens and demons come out.
There is a severed arm lying on the ground near the breach, with a gauntlet on it - the gauntlet seems to be surrounded by fireflies. But there are demons nearby.
If they go to the town, they can find Eva.
She uses 5 magical pylons in the ground around the Firefly Queen's cave to "scoop off" some of the Queen's energy, and transfer it to a gauntlet.
She was trying to close the breach.
The gauntlet is then used to "plug" a demon breach that has appeared near her village.
Closing the breach
Eva knows that they might be able to close the breach from within.
They can use the gauntlet, but this would kill the firefly queen(s)
The flameskull volunteers to close it from within.
The party can find an alternate way to seal the breach. Mad might remember how to.
As an action:
Drawing on the power of the Firefly Queen, magical fireflies appear and swarm around the gauntlet. They zoom out from your hand in a 5-foot-wide, 20-foot-line. Each creature in the line must make a DC 7 Constitution saving throw. On a failed save, a creature takes 3d8 radiant damage and is blinded until your next turn.
While being powered by pylons:
Super beam, flight
Imbued with magic:
The party observes fireflies flying, when all of their lights go off at once, synchronously.
The firefly queen says she can imbue the gauntlet with power willingly - it won't be as powerful as
They are given an item
Can summon fireflies to help
Can communicate over long distances using fireflies
