The Ways

The Ways is the vast network of underground caverns and tunnels underneath the surface of Azure. Originally home to the Dwarves before their migrations to the surface Marches, it is a dark expanse hosting many dangers and secrets
Geography
The Ways underground landscape varies from small subterranean fissures almost impossible for adventurers to crawl through, to wide expanses of deep water that hid coral caves, hollowed out sections of ice in which creatures lived, and places where fungus, bones, or even pure force formed "caves."
This varied landscape is as dynamic as the surface of Azure. Some areas are always changing over time because of underground magma rivers or the emptying of underground lakes due to cracks in the rock formed by earthquakes. This meant maps of the Ways are highly unreliable.
Environment
The Ways environment varies vastly from the surface world, making adventuring through it a dangerous expedition. Just like trekking through a desert, adventurers traversing the Ways passages need to be well prepared.
The Ways are mainly without any source of light save for the occasional luminous rocks or fungi. Large portions of it are also without food or water, making well-stocked food supplies a must-have when exploring uncharted terrain underground.
Lack of light combined with a tomb-like silence made traveling something only for the strong-hearted. The nerve-wracking silence make even experienced adventurers grow agitated after a few days.
Just like deep dungeons, the air can grow stale and even poisonous in the Ways. It can contain explosive gases from underground volcanic activity or other deadly gases bubbling out of deep fissures in the rock.
Bad air and poisonous fumes can collect in portions of tunnels and caves more or less isolated from the main vaults and caverns. Siphon-like tunnels holding water cocanld also trap these gases for a long time.
Climate
The temperature underground varies according to depth and the proximity of thermal activities in the area. Throughout the year, the temperature remained stable and moderate in most regions, usually slightly clammy or chilly. The water underground is extremely cold and posed a hypothermia risk.
