Юниты "Might & Magic Heroes VI"

1. The mermaid was also in Heroes of Might and Magic IV.

Can the mermaid be hired in a castle? And the insider said that:
it was a neutral creature in one of the previous games, and we encountered it on the map.
Therefore, formally, the leprechaun lives with the Nature faction, and the mermaid only belongs to the number of units of Power, but in essence, it is a neutral creature.

Considering Marzin, it will most likely be a mermaid.

The artist??? What does he have to do with it...
