About god "Dievs"
"Sometimes he comes to earth to mess with the mortals and stuff."
There's an explanation for that — he comes to the lands to test the mortals (usually as an old man) — how close they are to the belief of gods and to test the kindness and awe of people. For the good people who follow the belief and give the kindness to others he would reword with a blessing of other gods they belive. As example the god Laima would smile on person who was kind to him (things would start going good in everyday life) It's just an idea from reading Latvian dainas.
