So since I am trying to pronounce the words according to the descriptions in the tips & notes for the first skill (Basics 1) (which is tricky since there is no sound and there are also no pronunciations, for example, on forvo.com... although I remember a bit from the show), I find myself wondering about the stress the words get. For example, in the word "kirine", which of the three syllables gets the stress?
Does anybody know? Or does this perhaps get explained later on in the course?
I found a page that does seem to have some info, but I take no responsibility for its reliability.
Seems to me though, that the emphasis is usually on the second-to-last syllable.
I think this might be useful. Hope it helps. https://www.memrise.com/course/1586994/duolingo-high-valyrian-audio-wip/
Although the language is pro-drop, that just means that pronouns can be dropped; I have not read about it allowing the dropping of linking verbs and/or copulas, yet. So probably you would have to have an equivalent of "is" to express the sentence you suggested... I think it might be "issa" in High Valyrian.
Found this table which helps explain. https://wiki.dothraki.org/High_Valyrian_Adjectives#Class_II
So it only changes based on case, gender, and if it's singular or plural. So it doesn't change based on the number of speakers :D So it would be the same for "I am", "You are", and "She/He/It is", but would change to "Kirini" for "We are", "You all are", and "They are", but only for the Lunar/Solar Class, and while using the nominative case. Hope this helps!
