NHF – new heroes for Heroes V 3.1.

You can give the Sanctuary heroes to someone (they ran away from the Nagas or something like that).

Or you can make a Sea Elf hero for the Elves (I don't know, but maybe you already have one – I don’t want to read the whole thread).

In general, I had an idea to create a Sea Elf hero for the Elves with a special ability to summon Hai Ro (/topic/at/442362/) - (the mechanic would be as follows: instead of a non-working Yeti, a sacred Kirin from the Naga mod is placed; then an Avatar of Death is taken and edited so that its special ability summons exactly this creature, and not from Necropolis, but I understand that we cannot clone the special ability and edit the clone – that is, if we edit the Avatar, Arantir will also summon not a spectral dragon at all).
