Shakra

"Fierce and intimidating, Shakra is a warrior seeking her master, who vanished under strange circumstances. Shakra’s clan are skilled fighters who can handle their own in the kingdom’s wilds. Usefully for Hornet, each member of the clan also hones a Craft-Skill and Shakra’s mastery of cartography will prove invaluable on Hornet’s adventure."

- Official description

Shakra is an NPC first revealed in the Hollow Knight: Silksong announcement trailer. She is a warrior who mastered the Craft-Skill of cartography. Shakra is seeking her master who disappeared.

Silksong
Shakra makes a single appearance in the announcement trailer; she is shown under the "New Friends" tab. She is standing in a dark gray and foggy cavernous area dotted with large chains, standing next to what appears to be a large structure with visible windows. As Hornet approaches, Shakra lowers into a stance whilst making a loud vocalization.

She was later described in a blog post, noting her as part of a clan of warriors who each hone a "Craft-Skill", with hers being Cartography. It also explains that she is seeking her master, who disappeared under "strange circumstances", while also hinting of her role of aiding Hornet in her journey with her mastery of cartography.

In a later blog post, she was directly confirmed to be the the source of mapping tools for Hornet, who will provide charts, compasses, and various other tools.
