NHF – new heroes for Heroes V 3.1.

Yep, I've already found some suitable ones – they seem to be made by the Dungeon faction... ;)

Well, they don't necessarily have to be for these two – they already have their own biographies, and as you can see, they also have icons. Besides, there are already few canonical heroes among the Sylvan, so maybe these two will be useful.

I remembered another elf – General Pao. General Pao led the elves during the battle against the demons. Silanna also participated in that battle (apparently, this was before the division of Ashan into the earthly world, the spirit world, and Shio, i.e., before the appearance of the Seventh Dragon, when the demons were not yet imprisoned). During the battle, Silanna caused an earthquake, which resulted in a part of the mainland breaking off. After the victory over the demons, these islands were named in honor of the elven general – the Pao Islands.
