I found out I had the bowmen (the archers from the first castle), I thought they were the upgrade of the normal archers. So I turned in 50 of the needed, for the key to the cave, where I got some items and the free dragon and enough leadership to use it.
Then I kited a pirate away on Rusty to get the map for Tekron, so now I'm there, running around gathering stuff.
My bears went away for the green dragon, so I'm up and running!
By the way, the dwarf that's been everywhere in the world on Tekron, is selling two dragon eggs of red, green (?) and black for 2.000 each. That is a great price, isnt it?! 10.000 normally?
EDIT: Oh, just read they were chickens:
