A strange quest.
That's what it was referred to as in the novel.
In all honesty though, it truly was a strange quest to say the least.
In the crystal caverns district of Sector 3 where ores were requested for to be mined on a constant basis, an antique shop keeper by the name of Novier, requested for an investigation into a deeper part of the cavern for a particular ore that was exceedingly very hard to find.
And as if that wasn't enough, the more one went down the confusing windy yet levelled structures of the crystal caverns, the more Kraugrs showed up.
These naturally existing monsters showed up in the caverns as a result of a previous fissure break occurring in it, greatly modifying the environment around it to make it habitable for them.
That was how the Crystal Caverns of Sector 3 along with the monsters present in it came to be.
