Looking for a Party: Nilos, The Greek River Dragon

It's official, I've won my first creature of the week round! My little cancer-eating bacteria you see in the post-below scored up 19 out of 40 votes. I kinda wish I'd done even better, but I'm just happy to, finally, after so many attempts, get that win. So now, let's move back on to other business, where I'm less likely to win...

This week we had a COW winner (7 wins), by the username emerging, guest host Creature of the Week. The topic he chose was "Titan War Beast". This is our third official: "War Beast" round (Amphibious War Beast and Arctic War Beast being the other two), and I think this is the best I've done on any of them. The theme was to design a war beast that the Titans would have used in the battle against the Gods in Greek mythology. The idea was to use the sort of God of War-style epic imagery of colossal forces as our inspiration.

I decided to go with Tethys, wife of Oceanus and mother of the great Rivers of Greece, as the Titan I would draw from. I imagined that she had transformed the great rivers into massive dragon-like beasts. I invented a dumb little story that went along with it, as I did with my hanging gardens of Babylon creature, so I'll post that, too, I guess:

When the Titans rose up Ares sent forth his forces into the foothills to head them off. Enyalius led this force, charging forward in his shining, pegasus-drawn chariot. When they reached the foothills they found the beasts.

Tethys, mother of the waters, wife of Oceanus, had taken the children of her Tiamat and transformed them into the great rivers of Greece. Now she had taken here children back for the sake of war. Greatest and fiercest among them was Nilos, the beast who was the River Nile.

Enyalius' forces scattered at the sight of the Titaness' river beasts. Only Enyalius remained, charging alone against Nilos; a mere white speck against the colossal river beast.
