Sprigg is an elderly gnome. He is bald on top with a long white beard. He has a bit of a distant look in his eyes.
Darin De Paul said that he originally thought of Sprigg as Fagin, a Charles Dickens character, who was just going to steal everything he could, but that the goodness in everybody brought out the goodness in him.
Sprigg was part of an adventuring party for some time and they considered themselves to be heroes. However, during a battle with hobgoblins all of them were slain except for Sprigg, who ran away. The gnome spent the next thirty-seven years isolated in his tiny cottage, becoming somewhat addled and apparently suffering from survivor's guilt.
After becoming attuned to Ioun during his encounter with Vox Machina, he recovered at least some of his memories, and named several of his former companions: Thetapax, Zephyr, and "that guy with the nose" whom he claimed was his favorite.
"The Fear of Isolation" (1x105)
Vox Machina found Sprigg in a small house near the Pools of Wittebak, but the old gnome had grown a little bit mad in his thirty-seven years of isolation. While they were trying to extract information from him, Vecna's assassins attacked from the shadows, trying to kill him, but were successfully repulsed.
After being helped by Pike to pray to Ioun, Sprigg's torso began to glow blue. He himself was the tuning fork that could be used to guide a Plane Shift spell through the Divine Gate to Ioun in the Endless Athenaeum. The party, along with Sprigg, joined hands and shifted there, where they were greeted by the voice of Ioun.
"The Endless Atheneum" (1x106)
Sprigg asked Ioun why he, a nothing and a coward, had been chosen to be her key. She replied that she had always chosen unlikely sorts for this role, but saw in him the seed of a seeker of knowledge who could yet be redeemed.
Following Scanlan's success in completing Ioun's challenge and her granting a bead of divinity to aid in creating a prime trammel, Sprigg asked whether he could offer anything to help her in her recovery. She offered to let him stay on with her as a steward, and he remained in the Endless Atheneum when Vox Machina returned to the Prime Material Plane.
Demistrik is an imp that shares a homestead with Sprigg. While the nature of their relationship is for the most part unknown, it was stated that Demistrik’s master died within the confines of Sprigg's home. Their cohabitation is likely a result of Demistrik's master's demise.
After meeting Ioun with the other members of Vox Machina, Sprigg offered to help her recovery go smoothly and now has a position as a steward in the Endless Athenaeum.
