Hey

nope. KR and NA is the EXACT copy.

Glas used to be a god but then it was punished by the gods for some unknown reason.

then Fomorian started to recreate a body for Glas from the bones of giant and (was it mythril or adamantium?) in Other World.

after it finished, fomorian called the Glas's soul from the world of gods.

however, something went wrong and the body gained life, but the soul of Glas went into the dying human living in Other World (it was previously conquered by fomorian.)

so Dougal or Glas's soul was pissed at fomorian for forcing him to come to the barren world ask you to destroy his body so that he may be at rest again.

so Dougal/Glas cannot be milletian.......

i wont say anything about guide-post since i cannot provide you with strong fact and im starting to doubt my memories :P
