Dwarves of the Underways

The Dwarves are a rather mysterious race. Whilst some of them choose to live on the surface, the large majority of them descended underground into the Underways during the event. It is said that they originally came from the Underways, which is why they evolved to have a shorter height and a form of acute night vision.
The Underways stretch far below the continent and form what is essentially an entire continent below it. It contains large caverns and underground cities forged together by tunnels and pathways constructed by the Dwarfs. It's uncertain how long the Underways have existed, or what exactly is down there, but there are those that are attempting to map it. Whilst some of the cities extend above the surface, some are so deep underground that non-Underway races have ever set their eyes upon them. There are also entrances to the Underway littered throughout the continent, with the Scorched Lands being the most abundant.
Out of all the races, Dwarves are least affected by Titan's influence, most of them being completely immune to it. However, this causes them to be almost incapable of using magic with Deus Crystals. Of course, they've circumvented this with the invention of the runic script, allowing spells to be cast away from the user. Most Dwarves are non-religious and do not believe in the Titan's influence of favour due to being near immune to their embrace, though they do not directly deny the existence of the Titan's.
It's unknown whether the Dwarven societies of the Underways act as a singular unit for many separate entities but there does seem to be some form of trade and discussion between them. There are other races that live amongst them, and some that do not surface and thus haven't been recorded in the annuls of the Athame University. Society as a whole is hard to gauge, and changes in different parts of the Underways just like the regions above them. One thing is known, Titan's influence does not seem to stretch below their lands, and those born in the Underways are often unaffected.
