In a specific location in the northern part of the Central Continent, there was a vast mountain range, with a dense layer of ice at its highest positions.
From time to time, birds completely white flew towards a small hole near the top of one of the mountains of that range. And if someone were around this place and paid attention, such a person would certainly be able to see that these birds carried the same type of object in their claws.
Such a thing looked like a small cylinder, typically used in this region for storing messages sent by unique birds.
Crows were one of those unique breeds of birds, but others, like those white birds, came and went from that mountain.
Finally, when they entered that hole, those birds would pass through a place that, at first glance, looked very ordinary. However, after a few dozen meters inside that mountain, things changed completely!
