Fan-made add-on for Heroes 7: "Umbrage Mage Vrin Pendragon"

Oh my, it seems that even though they changed a lot of their plans, they still managed to release a full version. The project now has a different name, and the old one seems to have closed, but this one also includes the new race mentioned above and supposedly has better technical execution. But I haven't checked it in the game yet.

and yes, now you can play with the new race on any map, it is selected among the regular ones, although there are only 4 heroes.
