When the Vestige and Lyris arrive at the Castle of the Worm to rescue Abnur Tharn, they ask the soul shriven in the nearby town how to get inside the castle undetected. The locals direct them to Cadwell, whom they rescue from Worm Cultists. Grateful for their assistance, Cadwell assists them in infiltrating the castle and again during their escape by opening a locked gate from the outside. The Vestige then has the choice between bringing Cadwell back to Tamriel or leaving him in Coldharbour.
Upon arriving in Coldharbour with the Fighters and Mages Guild force, the Vestige is separated by Molag Bal's defenses, and lands alone to the south of the Hollow City, near Cadwell's hovel. The old knight directs them north to the city. Afterwards, he assists survivors from Tamriel in returning to the Hollow City by using portals to traverse to Coldharbour.
Cadwell directed the Vestige to destroy Molag Bal's reinforcement portals while the Tamriel force of Mages and Fighters Guild members fought their way accross the Chasm. He also fought Molag Grunda alongside the Vestige after they reached the gatehouse at the end of the Chasm.
Once the Planar Vortex was reached, the Groundskeeper revealed herself to be Meridia. She guided the Vestige and their group, including Cadwell, as they destroyed Dark Anchors. Once the Light of Meridia's power was released at the focal point of the Vortex, Meridia transported the survivors back to the Hollow City before they were killed.
After the Five Companions had performed the ritual to imbue the Vestige with the power of Akatosh, the surviving Companions were attacked by Daedra. Before they could be overwhelmed, Cadwell arrived and brought them through a portal to the Harborage. Once the Vestige had defeated Molag Bal and recovered their soul, Cadwell declared he was now pledged to serve Meridia. He told the Vestige how to use the Light of Meridia to journey to the lands of their enemy alliances should they be interested in exploring them.
- "One fine day in the middle of the night. Two dead kings got up to fight. Back to back they faced each other, drew their bows... and stabbed themselves."
- "I've had the oddest feeling we've discussed this before, or did I already mention that? No matter. I am sir Cadwell the Undaunted. Knight of the court of Coldharbour, Champion of Chivalry, Defender of the Defenceless, Sheppard to the Soul-Shriven."
- "Well, don't dally about here, you've got a princess to rescue. It was a princess, wasn't it?"

"Hello, what's this? Out for a stroll, then? Lovely day for it.'"'

Tell me about yourself, Cadwell: "Well there's not much to tell, is there? It's the same old pish-posh. Gallant knight, epic quests rescued maidens. I came to this land when my head was quite unceremoniously separated from my body. Bad luck that, but you make the best of things."
How long have you been here?: "Oh, quite a long time. In fact, I wouldn't be a bit surprised if I were the oldest of the Soul Shriven. Of those who didn't go feral, that is. I know every tunnel and path, every nook and cranny. The others look up to me, I suppose.
How do you know Lyris?: "Ah, Lyris. girl's as mad as Sheogorath's jammies. Heart's in the right place, I suppose. Says she's got to rescue the Prophet to save us all from eternal torment. How an old blind man could do that is quite beyond me."
What do you know about the Prophet? "An Imperial gentleman. Apparently he was once a powerful mage, but the years haven't been kind. Lyris says he knows of a path back to Tamriel. I rather think that if one existed, I'd have found it by now."
You don't think there's a way to get home?: "I hadn't actually given it much thought. Anything's possible, I suppose. Truth is. I've been here so long, this place feels like home. But a good uprising now and again is a pleasant diversion, so where's the harm, eh?"
- He is voiced by John Cleese.
- He is originally from the Cyrodilic town of Chorrol.
- Even if the Vestige chooses to take Cadwell to Tamriel, he can still be found both in either Harborage or Coldharbour, participating in all latter quests in those locations as if he had never left Molag Bal's plane.
- He has a pet chicken named Honor.
- Cadwell bears strong resemblance to the iconic Don Quixote de La Mancha, written by Miguel de Cervantes in 1605 and 1615, and considered to be the greatest character of spanish literature.
- Much like Quixote, Cadwell is an idealistic and humorous middle-aged man, who dreams of knighthood and adventures, courageous in his own madness, usually portraying the role of the fool who actually leads to interesting plots.
- The design of Cadwell's moustache and beard resemble a lot the usual portrayal of Don Quixote, as the pot he uses as helmet is in a similar position of the spanish hero.
