Laura Drake's sword
From Jenny Everywhere Wiki
In the Collapsed Cosmos, when she competed with Jenny Everywhere for mastery of the Legendary Time Crystal, Laura Drake was wearing a military-style uniform including a sword at her hip, which she soon proved capable of using, dueling with Jenny (who wielded a magical collapsible staff). In counterpart to Jenny's staff's glowing “an eerie shade of blue”, Laura's sword began to glow “an angry red” as the duel unfolded. (PROSE: The Hermetic Garbage of Jenny Everywhere)
