“ The Earthblood Warrens are a series of caverns in which dwell men who live around the Earthblood Vein, a river of magma. They use the magma from the Earthblood Vein to warm and light their homes and cook their food. The Warrens are several miles long, stretching along the banks of the Earthblood Vein, and since nobody wants to walk that far, the Earthbloodmen capture large, magma-swimming serpents, which they train and ride.”
“ A small, primitive village has yet to discover fire, which is a good thing because there are highly flammable (but not otherwise dangerous) gasses in the air. The heroes, blissful in their ignorance, don't know that and think it a wonderful idea to show the locals open flame.”
“ Diseased people, (leprosy or any other such fear inducing disease) when traveling, will often times wear a cloak that entirely covers their body and ring a bell as they travel, used as a warning for any others to stay away. Could be used for a disguise or safe passage. ... you meet strangely cloaked people, sometimes ringing a bell. 'Please give us something to eat, mighty heroes!' This is time to show how good they are.”
