Argul

Argul was a ruined castle located in northern Eskorn, Returned Abeir.

History
Argul was built by dragonborn slaves to serve as a lair for the dragon lord Argularragh. Over time, people named the castle after the dragon. When Argularragh vanished without a trace, other Eskornar dragon lords razed the castle to stole whatever wealth Argularragh had hoarded within its lair and to ate its dragonborn inhabitants.
