Here's what I've gleamed from the Great Forge so far:

Upgrade 5 Viking Shacks to be able to level up the Smithy at 2,770 Vikings. This will cost 25 Iron for the Shacks and 49 Iron for the Smithy.

Next is to upgrade 5 more Viking Shacks in order to level up the Fish Basin/Wood stacks to get to 2990 Vikings. Cost is 25 Iron for the Shacks once again and then 90 Iron for the for the Fish Basin, allowing for enough Fish to level up the Wood Stack.

Only after that can one have the ability to upgrade the Academy, which requires 3,210 Vikings. This will require 5 more Viking Shacks at 25 Iron.

After that the game will allow players to level up the dragons past Lv100.

I made the mistake of leveling up 10 Viking Shacks hoping that I might possibly be able to level up the Fish Basin/Wood Stack buildings first.
