Donovan clapped a rough hand on Glasses’, no, Nico’s shoulder to indicate that he wouldn’t accept an objection. [b]Donovan’s rune was almost blinding now, illuminating both their faces to display the steel and excitement in Donovan’s cocky grin.[/b] He wasn't sure why Nico chose to buff Donovan of all people, but he didn't care either.

Beside him, Fancy Smoke got jumped by Panther Girl. He ignored them and walk past, expecting Nico to follow him. [b]Thanks to his shining rune and the flaring lights of Nico’s sigils[/b], he easily found his way through the dark fog. With this energy, he felt unstoppable. His aura touched pretty much everyone and he could feel its gradual effects already taking its hold on people.

Nico and Donovan's runes/sigils were glowing bright enough to illuminate their way through the fog. I think that's enough IC evidence for both Nico having a connection (not necessarily amplification) to Donovan's magic and the aura of calm being sourced from Donovan.
