Thornwatch Keep
Thornwatch Keep is a newly raised gray stone fortress standing across the river from Thornvale Village on the site of Garrant's family home. It was legally deeded to him after his brother Garrick's death, but the place already bears signs that someone else has taken an interest in it. A broken bridge blocks easy access, a sentry has been seen on the battlements, and hobgoblin tracks near the crossing suggest the keep is being used as a foothold or hideout. What should have been an inheritance has become a contested holdfast tied to family history, violence, and whatever warning Garrick tried to leave behind.

Thornwatch Keep
Cold, watchful, and unsettled. The stone feels new, but the air carries the weight of old loss and recent occupation. At dusk, the keep looks less like a home and more like a warning.

Guarded, stubborn, and duty bound, with a quiet grief beneath his resolve.
History
Defense and Access
The keep is meant to be hard to take, but not impossible. The broken bridge is the obvious choke point, and the main doors sit at the end of a narrow approach that can be covered from the tower balcony and arrow slits. A small number of defenders could hold the entry against a much larger force if they have time to prepare. The battlements give clear sight over the river crossing and the ruined village beyond, which makes the keep useful as both a watch post and a warning line.
Exploration Notes
The best places for the party to investigate are the broken bridge, the stable yard, the tower stair, and any sealed lower rooms near the old foundation. The battlements show fresh patrol signs, but the interior likely holds older signs of Garrant's family before the keep was built. Players at party level 0 should find dangers that can be avoided, outwitted, or delayed rather than fought head on. A hidden route through the old family cellar may connect to the foundation or to a service tunnel used during construction.
Use as a Stronghold
The keep can serve as a home base only if its current occupants are removed or negotiated with. Supplies are sparse, but the stable area, kitchen stores, and tower rooms could be made livable with work. Its location across the river makes it valuable for tolls, patrols, or a small militia post. If Garrant secures the deed and clears the threats, the keep could become a symbol of his family's return rather than just a ruin rebuilt over old grief.
Denizens
Guarded, stubborn, and duty bound, with a quiet grief beneath his resolve.
The sole heir and lawful owner. He is driven, wary, and still grieving his brother, but determined to uncover the truth behind the keep.
A stern local official who helped oversee the legal transfer. He knows more about the deed, the family history, and the Elders' concerns than he says aloud.
A dead man whose choices still shape the keep. His warnings, buried notes, or hidden preparations may be the key to understanding the occupation.
A lookout seen patrolling the battlements. Whether disciplined soldier, hired mercenary, or something stranger, the sentry suggests the keep is actively held.
Rumors & Plot Hooks
- 1.The broken bridge was cut on purpose to keep something from leaving the keep.
- 2.Garrick hid a private room or sealed cache somewhere in the old foundations.
- 3.The hobgoblins are not the true masters of the keep, only hired muscle.
- 4.A tunnel under the river once linked the keep to Thornvale Village before the flood and ruin.
- 5.The sentry on the battlements changes at odd hours, as if the post is being shared with outsiders or worse.
Classified Entry
Beneath the newer stonework lies a concealed chamber from the old family home. Garrick used it to hide evidence that the keep was built over something he did not trust, and the current occupation may have been searching for that chamber all along.
