Kyran unsummoned Bas, Manti, Mera, and Iss to let them recuperate in his Void World. After which, he focused on examining Zephyr and healing him.
It did not take long for him to discover the crux of the problem of why he could not share his healing ability with Zephyr even with the Sigil's help. A remnant of the restraining energy had taken root in his blood streams. Normally, this would not have been possible, however, the energy merged itself with the magic that managed to infiltrate Zephyr's body.
Using simple words to explain it, a different energy with a restraining effect was coursing through his body that prevented him from circulating his own magic energy.
It was a case similar to Cyneah's but also different. Because the nature of the magic that infiltrated Zephyr had no such capability. It just happened that the restraining energy of another magic managed to combine with it, resulting in a similar effect.
