Where to find the whetstone in Elden Ring Nightreign

If you've stuck with Elden Ring Nightreign's default character, Wylder, then you'll quickly fill his journal and unlock his Chapter 3 Remembrance mission, which throws you in at the deep end with what's called a personal objective. Speaking to Iron Menial, the Roundtable Hold's caretaker, you'll then have to find a whetstone in Limveld.

You're given very little to go on, other than Iron Menial's advice to make your way to the mining tunnel, which is somewhat misleading considering there are multiple across Limveld.
