She probes further, while still keeping a watch on her surroundings as she follows the path (are there signs of habitation? a river to follow toward town? hostile creatures?).
Is the pool some kind of reserve of her ink, what's not in use and what she can use to heal herself maybe? Is it where she gets the mass and volume to make bigger or denser shapes comes from? What happens if she makes her hair longer, does that do anything to the inkwell? Can she give herself extra-sturdy and sharp claws?
What about the ledger, does that track... debts? Connections to people? To places? Can she leave a droplet of ink on a tree here? Does she retain a connection to it if she does? Does it show up in the ledger?
What about the prismatic glow, can she push that into things? Can it be more in some parts of her than others? Does it do anything or feel like anything when she tries to push it into parts of herself?
And that windy gusty thing, what's that? It doesn't feel like part of her inky senses, so is it something to do with local magic?
