I love the story you had to go along with this? Did you make it up or is it from Norse mythology?

it is based on the norse mythology, I only added the hogtie position to it. The original story was that after Alberich was bound he still refuses to hand over the ring, so Loki threatened him to let collapse the whole mountain of his kingdom down on his head if he didn´t obey, and thus let the dwarf give in. After the ring was handed over, the gods actually freed him again and then the dwarf spoke the curse.

Let´s say, I only modified the action a little bit

If I'm remembering correctly Alberich is from the opera The Ring of the Nibelung (Der Ring des Nibelungen) based on the Norse legends, where the original Fafnir comes in as the dwarf or giant whom later transforms himself into a dragon to guard the treasure and later being killed by Siegfried, so quite an appropriate picture really for origin of your dragon character's namesake.

I do wonder as well where it got lost along the way that dwarves in the Norse mythology were capable of powerful sorcery themselves but more often seen in more modern fantasy as distrustful of magic or not as capable with it, save perhaps crafting runes or armour and weapons?

bingo, absolutely correct, hehe.

What know about the norse dwarfs, they indeed were powerful with magic, but the most famous of their skills was to carve magical runes and smith treasures and weapons with magic inside them to use.

While the "Black albs" - also often depicted as dwarfs, were more the magic casters and less known for their magical craft and handiwork.

thanks much, sir

but mythology has plenty of good scenarios like Loki, Prometheus, the kings of Ulster, Enkidu and so on and so on^^

Oh wow haha Nice really liked the angle of the hogtied character in this drawing of yours (doesn't seem like he'll be going anywhere for awhile hehehe^^). Sorta has that Lord of the Rings feel to it and the shinny glare you put on the ring was a nice touch :)

thanks much big partner

In fact Tolkien used many references from the norse mythology for his Lord of the Rings.

You could say, Alberich´s Andwarinaut is the "father" of the one ring.^^
