The Wiki of Dead Gods

I'm starting to edit this shit into a real wiki, at http://blood-of-dead-gods.wikia.com/wiki/Main_Page

Big fantasy tropes...

So I've been trying to sort of re-skin a lot of the standard fantasy tropes and give them an interesting (to me anyway) personality. So what to do, if anything about some of the bigger fantasy tropes?
And I mean that literally, BIG tropes, specifically giants and dragons.
A dragon equivalent would e way enough to explain - there was life on the world before the gods got there, there could easily have been a large, smart, dangerous, flying predator of some type. Easy enough to assume that some god or other tinkered with them, made them even bigger and smarter, and gave them access to magic. The latter would be necessary if the whatever was to be truly draconian in scope, as a creature that big would need magic to fly, at the very least.

But how to do it without just making a dragon, or something that screams "this is supposed to be a dragon, yet is kind of stupid"?
Wyvern would be easy enough to explain. Birds or local bird-like organisms that were boosted by the gods, or just mutated by exposure to the blood.
Maybe just have someone doodle something, and figure out what it is afterwards...

Just a random thought...

Magic is finite, the corruption is not. The well of magic was kept full by the gods, until their death. Now that they are no longer there to refill it, it is a limited resource, and will eventually run dry. It may take 1000's of years, maybe longer, but it will run out eventually. However, the corruption is alive and self-perpetuating. As long as there is life in the world, the Blood will be there, and will be a path to power. This eventually, all magic will be corrupt, and some time thereafter the entire world will succumb to the blood.

DOOMED! DOOMED I TELL YOU!

Don't know if I actually want to use this or not, just a thought...
