Explorer’s Runes

The Explorer’s Runes was a language made the Explorers and the Tundra Pack. It showed the Taiga Pack to the ice cavern Amethyst was waiting for them in, and was the language that the Explorer’s journal was written in.
Amethyst is known to have been able to read the language before he died, but it is not specified if Diamond was able to.
Basil had picked up on the language as a puppy and had remembered how to read it. Stacy learned after her.
The family tree for the Magical Wolves was also made in the Explorer’s runes.
