Moria makes an appearance in Nonnus' Dionysiaca, in an episode that is as follows.
Moria only could helplessly watch her brother die, but then Damasen, a Giant son of Gaia, arrived on the spot; Moria implored him to help and he killed the serpent, hitting it with the trunk of a tree he tore out of the ground.
Then a female serpent, the slain monster's mate, appeared and used a magical herb, referred to as "Zeus' flower", to bring the dead serpent back to life.
[1] It has been speculated that the myth of Moria, Tylus and Damasen may be rooted in Lydian mythology.
[2] A similar story could be compared to that of Polyidus who used an herb to resurrect Glaucus, the son of Minos.
