Let’s bring this discussion here, instead of derailing the background thread.
To answer your question, yes, three sons and a daughter.
And to get the “so many children” thing out of the way even before anyone asks, because elves appearently aren’t very fertile - there are three Windrunner sisters and they had a brother. Both Vereesa and Alleria are mothers, and both conceived their child(ren) with a human father.
I’d say that puts an end to that point.
Also, I’ve tried having family members be NPCs or phantom characters with another character before, or eve nplay them myself and reduce their relationship to the off-screen and I can’t say either of those worked well in my experience. It felt forced and immersion breaking.
I’m comfortable with the current situation as it is. It doesn’t require any mentions when he thinks they died years ago and he has no real motivation to look for them because of the same reason.
And when/if I find someone I trust enough to RP either of them, it can be solved with the son/daughter finding their dad instead of the other way around. Lyth travels around a lot and spends precious little time in Silvermoon, so it’d make sense for them to have trouble getting to him.
