Tronorma is an island in Legonia on the other side of the Azure Sea. Ents and goblins have been living on the islands for centuries.
When the ice age began, a few dwarves came and lived in peace with the ents, building the fortress of Fanamdur. The ents and dwarves have mixed their cultures together. They have a culture that believes in the dwarf god and that spirits live in ents when they are dormant. The goblins remained mischievous living in the woods.
Well, the fortress isn't very special, also the ent needs improvement. But i like the main idea and the goblin shelter is a nice touch. Think, i'll keep your design for goblin architecture, have that cotton twice and a lot of brown.
