I would first like to declare that I write this not as a representative of the Dwarven Empire (Austin has that role) but instead as someone with private economical interests in seeing the following happening.
Currently, all factions appear to be very careful when it comes to using public portals. If ever used, the one visiting will always be under strict surveillance and the faction guarding the player will be entirely occupied doing so. Because of the resulting low visitor pressure, public portal areas are underdeveloped and serve little economical purpose.
What I propose is a trade agreement between as many factions as possible. This agreement would require signatory factions to always leave their public portals open (unless at war with either a non-signatory or signatory faction), but also ban the use of public portals as a means of transportation for an aggressor, signatory, faction. The treaty would be of entirely civilian purposes, and as such, breaking the treaty by either closing a public portal while not at war or using one in an attack on a host, signatory, faction will not result in automatic consequences. Host factions would take responsibility for the security, land and shop access of visiting players, and as such would not be allowed to kill visitors unless these clearly were to move outside the area designated by the host faction.
I do realize there are inherent problems with this proposed agreement, but I am merely putting it here partly because I believe there would be substantial profit to be made by everyone (trade, tourism) and because I belive there is some interest in seeing something like this being negotiated (I heard from Greens that he was setting up a public area in Northern lands and our faction has one as well, albeit unused at the moment).
Suggestions or comments are welcome. Please note that this is entirely unrelated to moderation/server rules as it would be an in-game agreement relying on good will rather than enforcement (in short: not for the discussion of portal rule changes).
