Possibly he should talk with someone before he does. He wouldn't want them to think he'd left entirely.
And then he's off to find some justice-related professionals.
The justice system, if he asks around, appears to be skimpy on trials per se, but includes evidence-gatherers and has certain standards before someone can be brought to formal legal attention beyond just those sniffing around. There are police, who deal with more immediate and physical threats than the evidence-gatherers, do patrols, perform arrests, and so on. There are judges, who may throw out cases if there are procedural issues or the entire thing is frivolous, or assign sentences; judges usually work in pairs unless the caseload is enormous. Apparently paladins have some extrajudicial powers which only apply if they can demonstrate after the fact that they have kept all their powers (thereby proving that they have not disobeyed their Order superiors or the Winter Light's dictates) and only if there are dark things involved.
Well, there's no clear equivalent for his accustomed role. But he should probably talk to a judge first, and arrange a demonstration of his value.
He tells the clerk, "Give me a moment, would you?" and steps around a corner. And then he does the imposing entrance thing at the clerk.
"I am a Judge of the Order of Judges. I come from another world. I can tell whether someone is giving false testimony in some detail, determine what punishments will be effective on a convict, and calm or subdue groups of people with that thing I just did. I am confident that the judges in this city will consider me worth their time."
The imposing effect doesn't stick much longer; it's purpose has been served, and it's not easy to maintain.
"I'm sure you're more familiar with the governmental structure here. I am uncertain whether I would be most useful as a judge giving sentences and evaluating testimony, in assisting evidence-gatherers by checking for false testimony in the field, or in some other peace-keeping role; where I come from, I would do all of these things regularly in the course of my duties. Who should I speak to who would be well-equipped to evaluate what I can do, and, if they are not the decision-maker themselves, will be listened to by those who do make the decisions?"
"I suppose that makes some sense. Feel free to mention my visit; if anyone is interested in talking with me, I am staying with the Order of the Winter Light for the moment and can be found there."
"Yes, well, I'll be sure to check which door is his before I walk in. I'm not used to having to do this to be taken seriously; the Order is well-established at home. Thank you for your help."
And: Imposing entrance!
Theod sure is getting a lot of practice with this 'imposing entrance' thing. It might be going to his head a little. And he might not be trying to stop that. At all.
Yeah, this is fun.
