Addressed at the anonymous user that just changed the distance between Invrisil and Celum from 600 miles to 300 and decided for some reason to call one a moron for not reading their own citation.
changed 600 to 300, timeline is incorrect, pirate has said so in discord. The citation says 300 miles. What moron didn't read their citation.
The original line did say 600, which you can still see on royalroad:
“That’s six hundred miles north of here. Even if you started now, I doubt you’d make it before the rest of the land is coated in ice.”
