Tamber is a Celsian itinerant scholar, serving as a tutor for children in the mountain village of Verrow's Span. She is knowledgeable in history and familiar with the ancient lore of the region, especially the age of titans that predates civilization. Her academic demeanor is marked by her interactions with travelers, through which she shares insights and wisdom.
In Verrow's Span, Tamber examines Sylvie's layered necklace and a Rune-Marked Box but does not recognize their make or style. She inquires if they have visited the Celsian Athenaeum, demonstrating her knowledge of significant scholarly locations. While discussing mountain glyphs with Sylvie, she suggests they are remnants from the titan age and hints at the existence of massive city-sized remains from that era. Tamber expresses curiosity about the witch that attacked Sylvie, admitting she has not encountered witches personally but has heard rumors of their fearsome nature. Later, she invites Heyou to study with her after the community dinner, showcasing her willingness to share knowledge.
Tamber, the Celsian itinerant, is associated with ancient knowledge and mystical runes. She is a former initiate at the Celsian Athenaeum, recognized for her scholarly demeanor and knowledge of magical practices. Unlike Ygva — expelled for the essence-draining practice of "depletion" — Tamber completed her initiation and remains a Celsian in good standing, holding techniques Ygva never learned. Tamber possesses runes and texts, including insights into the Rune of the Moon, which relates to themes of false hope and paralysis of thought.
During the events at Verrow's Span, Tamber engaged in research and discovered the Askavir, a giant bird potentially tied to Tlellic. She provided critical information about Ygva, her former peer, who was expelled for using depletion, a practice contrary to Celsian ethics. Tamber reveals that both she and Ygva learned from the same mentors but diverged in their practices. This history establishes a significant rift: when Ygva returned, she hailed Tamber as "sister," and Tamber answered by naming Ygva "apostate." Tamber explains the origins of the amulet Draz possesses, describing it as a relic commissioned by the God-King Otheidas to protect lesser mages from divine threats, noting that it will not safeguard against Ygva's Umbra magic.
Tamber contributed to the party's strategic discussions, highlighting the importance of understanding their situation regarding the refugees and The Heart they had obtained. She suggested leveraging hidden techniques not learned by Ygva as a potential advantage for the group. Tamber expresses surprise at Ygva's presence in the mountains, indicating her unfamiliarity with the area. Additionally, she discusses local customs of Verrow's Span, specifically the community's makeshift morgue and their intent for sky burials once the crisis abates. Tamber's knowledge and past experiences position her as a crucial ally in navigating their current challenges.
Recently, Tamber has become known for her teachings on the Old Gods and the dangers associated with their potential return. She emphasizes the importance of social stability in her lessons and warns against grand ideas that could disrupt societal functions. Respected within the academic community for her insights, Tamber rebuffed a proposal from Draz to support the return of the Old Gods, labeling it a threat to social stability. She adjusted her teachings to caution others against such ideas, and Jamal overheard her expressing stronger concerns privately about Draz's ambitions. Tamber advised Draz to exercise caution in raising hopes, indicating her commitment to preserving community functionality amidst potential dangers.
