He is found at the Blacksmith's shop upon first arriving at Raven Rock. Just like the other villagers of Raven Rock, he can also be found at the Earth Stone working on it and worshiping at it. When he does, he acts and sounds like he has been indoctrinated.
Glover will give a quest to retrieve his Ancient Nordic Pickaxe from Crescius Caerellius, after having it stolen from him, and also give it as a reward for the quest, claiming he has no use for it. It is also implied that he stole the pickaxe from the Skaal Village.
After the completion of this quest he allows access to his basement, which is filled with rare items including the Blackguard's Armor and a Thief Cache. There is a note to Sapphire in his basement, which reveals that he is Sapphire's father. It is also worth noting that, according to the Bonemold Formula, he has a younger sister.
If you talk to Sapphire in The Ragged Flagon - Cistern, after taking the letter, there will be an option to give her the letter. If you do give it to her, she will reward you with an Exquisite Sapphire; a unique item.
Glover Mallory has a chance of being a victim of the Thieves Guild, through the Radiant Quest "The Fishing Job", despite the fact that Delvin Mallory, Glover's own brother, is the one who assigns the task.
- "Either you're here to get showered in sparks, or you're looking for something to buy. Out with it."
- "You've got a good thing going here now that you reopened the mines. Don't let that go to waste."
- "Steel, dwarven, ebony...if it's broken, I can mend it."
- "Bring your weapons and armor to me, I'll fix it up right."
Glover: "I'm glad to lend a hand."
Adril: "You must be using quite a bit of your raw materials repairing their weapons and armor. I'm sorry we can't compensate you."
Glover: "Not to worry, Adril. I'll recover my losses in due time."
Glover: "Understandable considering the differences between us."
Veleth: "I'm not talking about that. I have a knack for smelling trouble, and for some reason you reek of it."
Glover: "I promise you, I have nothing but good intentions towards everyone in this town."
Fethis: "What in the name of the Black Hands is that supposed to mean?!"
Glover: "Nothing... I... I was just making conversation."
Fethis: "Next time you feel like having a conversation, talk to someone else."
Glover: "Skyrim. Born and raised."
Garyn: "Have any kinfolk?"
Glover: "Just a brother. Lives in Riften."
Garyn: "That's quite a distance from here. What's his trade? He a blacksmith as well?"
Glover: "Nah. He... finds things people are looking for. Makes a good bit of coin doing it, too."
Glover: "The usual. Piles of armor to repair for the Redoran Guard."
Geldis: "Aren't you pleased to keeping busy?"
Glover: "These hands were made for bending steel... not mending bonemold. But, it's certainly better than not working at all."
Vendil: "I don't know. There are many who would've already expected us to leave this place."
Glover: "Sure, but then where would you go?"
Vendil: "A fair question, my friend... a fair question."
