From the outside, the Mycontae was unassuming.
That is to say, you'd never assume it was there in the first place.
The entrance to the Mycontae was hidden within the thick vegetation of the forest that spanned the entire continent. Goblins apparently had a thing for living in caves, because that was where the entrance was found.
There were no overgrown fungus or elf skulls on spikes to advertise the location of the entrance. Indeed, it was so well hidden that one wouldn't even think to check if it was there, and only if one knew of its existence beforehand would they have a chance of finding it.
The only thing that gave away its location was a set of inconspicuous mushrooms cleverly hidden among the carpet-like moss on the trunk of a tree so thick, it would take ten Mornes just to wrap their arms around it.
