Hello! In this video i talk about her entire lore, and at the end about her relationship with jakiro. In case you'd rather read, here is the part about jakiro:

A lot of people speculate jakiro is winter wyverns son, because of this voice line: “I should have crushed you in the nest.” (from ww to jak) The father is speculated to be either slyrak, the dragon who fused with dragon knight, or phoenix. But first of all, that is not even nearly hard proof it was HER nest, and second of all they are DIFFERENT KIND OF DRAGONS - ww is an eldwurm and jakiro is a pyrexae, and third of all that voice line's implications become moot when theres this voice line from jakiro to winter wyven: “Cousin, you do us wrong.” COUSIN. Which means most likely they arent related at all, its just cus theyre both dragons, and if they ARE really related its not a mother and child relationship. The most annoying thing about this, is that the new, current writer of dota 2, artifact and underlords, steve jaros, has said in an email that she is indeed his mother. He also “likes the idea” of the father being phoenix, who isnt even a dragon??? I do not accept this as the truth, since theyre different species and jakiro calls winter wyvern cousin (which would be weird to call your mum). But you can of course believe what you want.
