Where the Wild Wolves Wander
Indigo’s methods were unorthodox at best and insane at worst. She and her pack believed that a dangerous Shoal in her territory could be dealt with by introducing a controlled Azlu infestation to the area. This thickened the Gauntlet near the Shoal, keeping the Hisil and human worlds separate.
However, keeping the Azlu under control could not have been accomplished without a powerful spirit ally. When the pack disappeared, the deal they’d made with an unknown spirit was weakened, if not broken outright. It’s possible that the spirit ally would be willing to make a new deal with the wolves who stepped in to take Indigo’s place, or there may be another spirit willing to step up. The pack could also choose to irradicate the Azlu entirely. An Azlu infestation left unchecked will soon prove to be a bigger problem than any pack alone can handle, and who knows what plotting the Azlu have been doing in the depths of the spider’s lair.
