The Yellow Ajah has long been known for their skill in Healing with the One Power. So much so that trainees who show any talent in this area are strongly courted by the Ajah and rarely choose another raised to the shawl. Beyond talents, Yellows are called by the need to heal others.

Recently, the Ajah has branched beyond One Power Healing into herbal remedies and medicines. Following the Seanchan War, and before her raising to Amrylin Seat, Katreine din Ziago Tempest Winds spearheaded a campaign for all Yellow sisters to receive training in mundane healing. Many sisters had long shunned the use of herbs and the like, viewing it as inferior to their abilities with the Power, but Katreine was a force to be reckoned with. She found backing with Sumeko Karistovan, the First Weaver at the time, and the then Amyrlin, Sharina Melloy.

In addition to broadening the Ajah's horizons, Katreine also swelled the size of the Yellow's eyes and ears network to proportions rivaling even the Blue's. Rather than dealing in rumors, however, the network is designed to bring attention to any new illnesses, outbreaks, or treatments. As such, it is not a secretive network as seen within the other Ajahs, but rather one that is fairly well recognized and recruited for within the many halls of healing and medicinal schools founded alongside the social outreach centers created by the Blue Ajah.

Rivaled only by the alliance between the Green and Red Ajahs, the Blue and Yellow go hand in hand in many of their endeavors. While the Blue seeks to heal society, the Yellow heals it's people and together they seek to raise those who are in most desperate need up to a place of self-sufficiency.

Once closely aligned with the Healers of the Black Tower, relations have cooled significantly as a result of Rahlin's Mad War. Yellows took up the healing of the Sisters, Warders and other citizens injured and all Asha'man bear the blame for a still raw scar. With healing those in need as their main concern, the Yellow continues to collaborate with Water, but they remember always and have not yet forgiven.
