What is your opinion on the possibility of introducing a third tier of maps and a new faction into the game?

Did ordinary mortals, and not the Nivale, come up with these GARIANS? I remember IGROMANIA announced a contest.

))Of course, it was ordinary mortals. We haven't suggested this idea to Nivale yet. Please don't post reviews here yet! I haven't uploaded everything yet!

There's a little more to go, but I'll finish it later. Just don't post here until I've uploaded everything.

7. Hero, abilities, and hero specialization.
The hero of the race is aquatic. Abilities (not all have been invented yet): "Power of Water" - deals additional damage with a water jet, "Water Shield" - adds +1 to the defense of all creatures in the hero's army for every fifth level, "Water Jet" - moves a friendly creature four spaces forward in a straight line. If, when using this ability, an obstacle (natural or enemy unit) appears in the creature's path (before the 4 spaces of movement are completed), the friendly creature on which the ability was cast takes damage calculated as P = v*s, where P is the damage, v is the speed of the friendly creature, and s is the distance the creature traveled before encountering the obstacle, and remains on the last space of movement (where it was before the collision). If the obstacle is an enemy unit, it is pushed back one space. If the unit cannot be pushed back (edge of the map or obstacle), it deals unreturned damage to the unit affected by the "Water Jet". For example, the "Water Jet" ability was cast on a Triton (v=4). On the third space of movement, the Triton encountered an obstacle (s=3). In this case, the Triton will take damage equal to P=v*s=4*3=12 exp.
Ultimate ability: "Fluidity" - all creatures can pass through obstacles during battle (both landscape obstacles and enemy units).
Hero specialization - Water Gate. "Basic" Water Gates - teleport the hero to the nearest castle. The cost of teleportation is 100 coins per stack (regardless of the number) of level 1 creatures, 300 for level 2 creatures, 500 for level 3, 700 for level 4, 900 for level 5, 1100 for level 6, 1300 for level 7. Thus, the standard fee (assuming the hero has creatures of all seven levels) is 4900 coins. "Advanced" Water Gates - the ability to teleport the hero to any underwater city (there must be "Water Gates" built in it). In this case, teleporting the hero to any city costs the standard price, and teleporting the hero to an underwater city that is not the closest to the hero costs 50% more, i.e., not 4900 coins, but 7350, with a standard set of creatures. "Master" Water Gates - teleports the hero to any underwater city at the standard price. "Skilled" Water Gates - teleports the hero to any underwater city for half the price.

8. Other. The question often arises: "how can an ordinary (land) hero move underwater?" Answer: "For this, we introduce two artifacts that will be sold at the transition points from underwater to land: "Sphere with Water and Air" and "Sphere with Earth and Air". "Sphere with Water and Air" is needed for land heroes to get underwater, and "Sphere with Earth and Air" is needed for underwater heroes to exit underwater to land. To return from underwater to land, a land hero does not need a "Sphere with Earth and Air", just as an underwater hero does not need a "Sphere with Water and Air" to return underwater from land.
Another question may arise: "How can these creatures live underwater for so long without air?" Answer: "The castles of this race are located in so-called "pockets" (underwater caves that contain air). In addition, it can be assumed that the castles are supplied with air from the surface through spider tunnels."
It is unnecessary to explain that fire spells do not work underwater (exception: "Meteor Shower", but its power is reduced by three times and it becomes an ordinary rockfall).
It would also be good to introduce the "Flood" spell. Yes... I forgot to say. The Tear of Ash (Grail) in this castle gives, in addition to the generally accepted advantages, the ability for the hero to exit underwater without the need to buy a "Sphere with Earth and Air", and the hero's movement on the surface will be the same (in terms of movement range) as underwater.
