NHF – new heroes for Heroes V 3.1.

Almost exactly like Siel from Heroes 6) (I mean the house-ships). Overall, my bio doesn't contradict the so-called canon. It's up to you now.

I heard somewhere that there were sea elves in Ashan.

If the elven lineage is so ancient, it should be known. Besides, the name Sylvan, considering the faction's second name, is not very suitable.
If the biography remained the same, except for linking the heroine to a fictional lineage, I think everything would be fine.
The first biography is more beautiful, the second is more consistent with the realities of Ashan.

MSCH, if the proposed interpretation by Lokken doesn't suit you, I suggest rewriting your own, or, if it's not that important, I'll add the one that suits Ashan better to the mod.
