So do all the resources and weapons (and kaithe!) we get from there, it's kinda wild from a lore perspective. You could theoretically imagine pretty much anything there, create it out of thin air and canonically bring it back into the real world.
Whats also kinda crazy is that duviri isnt new, its been around for a long ass time. Albrecht Entrati has been there, created a lab, and then teleported away with it.
Is it actually confirmed that Albrecht visited Duviri and not just any generic void, I don't remember anything about that? I thought Wally has limited control in Duviri, just kinda creepin' from the edges, and Albrecht got into direct contact with him iirc.
In all the ages of Thrax's reign, only two strangers have ever known to come to Duviri.
The other stranger came far earlier in Thrax's reign, before even the Bleeding Earth.
This stranger had haunted eyes and a downcast mien, and spoke of the Wall and the worlds beyond. He wore his hair like looped snakes, and his voice carried an accent unlike any in Duviri.
With the King's permission, he constructed a great laboratory of light-smoking mirrors and Void-lanthorns, which he claimed was the match of one he had once owned in a former life. The island where it stood was known as Scholar's Landing.
The time would come, the stranger said, when Duviri would be needed. There was work of repentance to be done, and he could not do it alone. What he meant by this I cannot say; and cannot now ask, for Scholar's Landing vanished overnight.
