One of the watchtower spires in the Black Shroud run by Gridania (designed for observation for Ixali balloon incursions into the forest, and also Garlean airships), is named 'Dunstan's Spire' (specifically the one watching over the Matron's Lethe in the Central Shroud). This is almost certainly named after a former commander of the Wood Wailers before the Calamity who featured prominantly in 1.0's Gridanian main scenario quests.

Long story short, he was cursed with 'woodsin' and became a 'wildling', a cursed man claimed by the forest's elementals and thus was banished from the city (and from then on was believed to be attacking Gridanian patrols - although an Ascian was probably the more likely culprit), only to be captured by Yda and Papalymo and returned to the city where he ended up cured of his woodsin... and was from then on never mentioned again.

But presumedly he went onto some manner of importance in Gridanian society given that he must have had some prestige to have a watchtower named after him... shennigans involving the elementals not withstanding.
