Nodens is often called an Elder God. But I suspect that this, too, is not a pantheon, but indicates some other status. It certainly does NOT indicate friendship towards Earth life. Read Lovecraft’s stories of “The Temple”, “The Moon-Bog”, or “Hypnos”, for examples. All three, in my educated opinion, have to do with Elder Gods or their equivalents. For that matter, I consider Hecate, referenced by HPL as “Gorgo, Mormo, thousand-faced moon” as an Elder Goddess. And also possibly the Magna Mater. So the Elder Gods are clearly able to be inimical.
