An old friend of Nightmare's that seems to know a bit about his past. She also has an incredible knowledge of plants. When the Terminally Stupid of the pack get hurt, Riverblade's the one to patch them up
Riverblade's story:
River was a young pup born into the Joku pack. She was very close to the leaders only two pups, Night and D. The three were a mischievous trio bent on causing as much chaos as possible. As time when on, the three received their adult names, proof that they were worthy and capable. Nightshadow, Riverblade, and D****light. Then, things went downhill. Riverblade had no idea what happened. Just that the pack was under attack. The leader was dead and so were many other wolves. Eventually, the survivors started fleeing. She tried to find Nightshadow and D****light, but to no avail. Just when Riverblade thought all hope was lost, Nightshadow jumped out of the bushes covered in blood and clearly frightened. She urged the other to run, which he did, only when convincing Riverblade to go with him. But when she realized they forgot D****light, she turned back to find him. But... she never did. When Riverblade tried to find Nightshadow again, she failed. Her only other friend was now lost, gone for what she thought was forever.
Then, one day, Riverblade decided that perhaps she should check out the forest for food. She had been running quite low and not having a pack did not help her case at all. Then, she stumbled upon a pure black wolf with glowing blue eyes. Nightshadow.
"Riverblade?! Is that really you? Do you remember me? You do remember me, right? I'm Nightmare!" That line... It was strange but he clearly remembered her, just, not himself. Not willing to question him, Riverblade followed Nightshadow, now Nightmare, back to where he made his pack. And she made herself at home at the healer.
Then, Ash came along, and not long after, Somnium. Riverblade does not trust these two. Ash is so very clearly from the Joku pack. And without an adult name, Riverblade refuses to let her guard down near Ash.
