It looks like the Malkioni pantheon is largely composed of appropriated local Earth and Hsunchen deities and deities from other pantheons, rather than the genealogy of Malkioni family and relatives and their descendents. In this respect, the Western pantheon fundamentally differs from other pantheons, for so-called Malkioni pantheon isn't really the Malkioni pantheon. Nor it is similar to the Lunar or Fonritan pantheons, because in the West, mortals usually can't become gods. And we know next to nothing about mythic age gods and heroes of the West.
Wondering the up and coming Invisible God and other Western books may expand and flesh out the Malkioni pantheon.
