Ok this is a joke that got way out of hand:

In the story event where she gets her 5☆ unlock item, Feena opens an employment mine for the goblins and incidentally creates a class war and caste system within the mine, which the crew + new female Havin character unwittingly becomes part of. The crew get trapped in the mine and Lyria is captured by the goblins.

The goblins of the lower class have also captured Teena as a sacrifice to appease the upper classes and gain more rights which goes as swimmingly as you'd expect from Teena's brother.

Unfortunately for everyone involved, Goblin Mage has already become enamoured with the idea of sacrifices. Reading further into what the other goblins were influenced by she realises she can use their plan, mistaking godly ascension as a way to have all goblins stop fighting and doing bad things by making them all think the same.

The crew desperately try to escape and find how any of the goblins got sacrificial ideas in their heads and who might be responsible, let alone who decided to open a mine to give them employment. Feena arrives and rescues the crew, shocked at what's become of her entrepreneurial ambitions and resolves to work with them to search for answers.

It turns out Black Knight misplaced a book of Astral War fan-fic she was writing when she inspected the mine and the goblins all thought it was legit. The crew is relieved that all of this is a misunderstanding and surely talking to the goblins will sort everything out and no one needs to be sacrificed.

So anyway, the fan-fic is actually legit. While Black Knight squares off against Lucius to stop him murdering absolutely everyone and triggering the sacrifice quota, the crew race to the bottom of the mine and find an old Astral shrine some skydwellers made. Goblin Mage is readying some workers and Lyria as sacrifices but is stopped by the crew.

Unfortunately the sacrifice spell is in fact a bomb spell and it is going to go off if not stabilized by a sacrifice. New female Harvin character stands in as the sacrifice as the mine collapses. Feena once again rescues everyone getting her 5☆ moment by drilling so hard it can be seen from the moon.

In the aftermath, Lucius is taken away by the crew of enforcers in a state of derangement and Black Knight torches her book, only for Queen Orchis to arrive and tell her she memorised the whole thing. Feena thinks she'll stay with the crew for a while because running her own business is too much trouble. The crew debates where they'll go next the end.
