Riddell holds the dual role of librarian and assistant to Takion, an enigmatic author striving to complete the mythic third installment of the Alice saga. Charged with curating a repository of stories harvested from vanquished Alice Users, Riddell inhabits a secluded dimension shaped by Takion’s authority, where they enforce strict protocols for narrative acquisition and archive preservation.

Serene and methodical, Riddell engages with protagonists during their audiences with Takion, maintaining a detached observer’s stance during clashes between Alice Users. While outwardly committed to Takion’s vision, fleeting hesitations surface when protagonists question the morality of exploiting personal tales to forge the elusive Eternal Alice.

As tensions escalate, Riddell’s involvement deepens during the climactic reckoning. Years of witnessing the protagonists’ resistance to Takion’s designs culminate in a pivotal betrayal: Riddell discloses concealed truths about Eternal Alice’s illusory essence and the boundaries of Takion’s dominion. This revelation empowers the protagonists to fracture the story-harvesting cycle and challenge Takion’s supremacy.

Riddell’s past remains shrouded, with no explicit accounts of their origins or allegiance beyond dutiful service. Yet cryptic exchanges and situational inferences hint at an ancient familiarity with the dimension’s laws and the arcane mythology surrounding the Alice narratives. The name “Riddell” echoes Alice Liddell, the real-life muse for Lewis Carroll’s literary icon, though this link remains unverified within the established lore.
