Steddos Thunderbrand

Lord Thunderbrand is an elderly dwarven arcanist that resides in the city of Kraghammer. As an NPC, he is played by Matthew Mercer.

Encounter at House Thunderbrand
Tiberius originally went alone to visit House Thunderbrand to learn more about magic and learn the whereabouts of some of the ancient artifacts he is looking for. After finding himself barred from entry due to magical runes, he attempted to force his way in using his magic. The runes proved to be too powerful, and he was almost arrested by the Carvers, Kraghammer's military guard.

The next day, after Scanlan successfully found a way to bypass the runes and knock on the door, Lord Thunderbrand answered. He was very upset that Tiberius had assaulted his home that night, and immediately did not approve of Vox Machina's attempts to convince him to allow them entry. After several failed attempts to trick him with magic, Lord Thunderbrand told them that they may return when they show him something valuable and interesting from their expedition into the Underdark.

Amulet of the Shield
While traveling through the Underdark, Vox Machina opened up a small cavern area where they found the bodies of six adventurers. One of the bodies, a female dwarf, had an Amulet of the Shield around her neck with the insignia of House Thunderbrand. On the back, the pendant read, "For Lorna, my love".

Through the Alabaster Lyceum, Tiberius was eventually able to contact Lord Thunderbrand and inform him that they had retrieved this artifact. Thunderbrand seemed very interested in the amulet and authorized Tiberius learn the sigil to Kraghammer. Tiberius, having cast flying too many times, needed a rest, so he, Vex, Grog, and Scanlan travel to Kraghammer the next morning, which upsets Lord Thunderbrand as he waited for them the night before.

Despite already being upset, Tiberius tries to get a reward and then shows him the Carpet of Flying and asks how much it would cost to re-enchant it. Moved by the return of the amulet, Lord Thunderbrand obliges but the amount he quotes causes Vex to throw her hands up and cry, "Oh my god, I just can't."
