Since right now here be dragons is cool to let us know that we reached world's edgem but it is annoying that I can see stuff ahead like animals, foragables and water on minimap past the point of here be dragons!, so instead there should be like a steep edge and past that edge a void of abyss, but the character stops and the usual message Here be dragons!
Since invisible walls kind of work better in a single player game, in my opinion, not a multiplayer game. Also would be good when we reach here be dragons! point that we could hear dragons roar too.
