Your great kukri wielding priest is adopted, HoneyBadger

!
It will appear in LA, when Ghurka-like units will be part of the nation.
I already have included kukri, and gave it dmg 3, att 2, def 0 and length 0 (it's the short dagger-sized version).
It deals quite high damage and have a good attack bonus because of the powerful blows it can deliver, and because it is quick and easy to handle. I've got a kukri myself, a short one. Frightful weapon. Once, I used it to chop a knife-resisting watermelon. I damaged the table, because the kukri went through the watermelon like it was butter ! I didn't even try to deliver a very powerful blow, but these damned things are both heavy and razor-sharp edged !
For the "tarwar", I suspect it existed before the Turks brought it with them, but with another name, and the Turks, seeing it, said "Hey, look at the huge talwar these Nepalese guys have !" (or a medieval turkish equivalent), so the turkish name remained.
I think this type of blade is not so uncommon : the Romans used to fear greatly the kukri-like Dacian sword called "sica", and also known the similar Iberian "falcata". Some Scythian weapons and the Greek "kopis" and "makhaira" looked very similar too.
