Its form is semi-transparent, akin to weathered celluloid or ice, allowing it to blend into any scene's background. It can subtly stretch and compress its shape to fit the composition of any tag, from a crowded workshop to a vast mountain vista. The faint, glittering frost trails it leaves behind settle as hidden illustrative details—a stray snowflake on a cloak, the gleam in a character's eye—that only the most observant players might notice.

The Gallery Ghost serves as the hidden narrative matchmaker of the Chainsmas Chronicles, deliberately orchestrating cross-league character cameos within each bag tag's scene to visually foreshadow alliances, echo past charitable deeds, and weave the ten separate leagues into a single, coherent holiday epic.
