By the time they've reached the Fifth Precinct Zerxus is aching and exhausted, which doesn't help him stay above water as he looks for Kahl. It's starting to feel hopeless - he can't dive beneath the surface in full plate, he can barely manage this - and he reaches a hand up to press against his eyes as he stops moving forward, just treading water.

There has to be a better way to do this. They're connected, he'd even felt it when he wasn't himself, so if he can just -

Kahl! I'm close, I need you to come to me. By habit, he's slipped into the simple focused call the Ring of Brass used when they were linked by Laerryn's spell. It doesn't work, of course, and he starts trying to infuse his words with more purpose, more emotion; he leans into the righteous fury on Kahl's behalf, and the profound depths of protectiveness he's felt since the moment Zerxus laid eyes on him.
