tbh Divinity Lizards are moe like dnD dragonborn.
they are descendant from dragons, can breathe fire, have a militaristic and advanced civilization.
Pretty much the same is true for Tymanther Dragonborn in FR, besides the whole "Magic slavery" part, i guess the Lizards in Divinity are like a mixture of FR Dragonborn and Drow. (or TES dunmer)

DnD Lizardfolk have bareley any lore, they are swamp hillbillies worshipping the god of cultural stagnation.

but yeah, Dragonborn look different (tho i hope they dont look like huge dwarves with dragon heads because i always thoguht that looked silly)
