: Alright then, replace "demon" with
: "monster", which are demonic.
The're just animals to be a demon or demonic etc. you have to have something magical about you.
: In M2 and 3 it is stated that Myrk Giants are intelligent
: and that the normal Myrks have intelligence aswell,
: though mb more feral and single-minded in nature, it
: is intelligence none the less.
Take Myrks as Raptors, intelligent in the Hunting sense but not exactly into the reading and writing. I suspect Myrks are intelligence wise a mix between a raptor and Gorilla.
On Giants, Myth III shows them in a less glorifying light, since it states that the explosives are made by Pack-Mages. Perhaps in Myth II SB had another attempt at altering Myrks, but didn;t get as much magical power, just increased their strength and allowed them to throw their explosives as a natural ability.
On the Packmages, well clearly not normal Myrks. They were probably magicly altered by Moagim to be sentient and intelligent to use magic etc. but this gives a few side effects eg feeble bodies, wings, slow.
