[@Tessaract] Ah, I'll go ahead and get those errors fixed.

Assuming that the two species have their own languages. She'll be mostly using flashes of colors, images, and symbols that someone like Whitepaw would understand, or someone clever enough to decipher them. Think Rainworld, or Hyper Light Drifter if you have played the games.

Her grasp on the written Human language, which may be the common, would be pittiful at best. That is to say she struggles with it. If she does uses Human words, It's because her usual communication attempts have failed. And when she does, it won't be a sentence persay, but a little word brain teasers. She's kinda unable to form coherent sentences on his own, but he understands the concept of a number of the verbs, adjectives, and nouns. But format of the language is what kills her.

Like say to describe her blade while projecting actual words. She'd use the word Sharp, Veil, Life, and Death.

The image created would be "Sharp" going through the horizontal center of "Veil" and splitting it apart. Above the word "veil" would be "Life", and below Veil would be "Death".

When solved, it is "Sharp enough to cut through the veil between life and death."

As for how long Whitepaw and Kastral had traveled together, likely 2-3 years. But [@vietmyke] gets the final say on that.

For the piece of the new world. There was a few bits of inspiration I took from some post apocalyptic worlds in other stories. But, I did take some time to figure out where a proper location for it would be. It would either be near a costal area, or near a location that had a device controlling the weather.
