Hello, by introduction i will say - when i first time opened map of exiles, i was confused. Why English alphabet ends on P not Z as it should be normally. also why its 17 would be nice to 20 … or so… well seems something missing…
So what is my suggestion : i will try to make it with images too…
So: As i checked the internet, and also long time ago i watched conan, and conan the barbarian movie… There was ocean and seas… ( Yes i found also someone i think mentioned, that it would be nice) . So based on original movie and new movie, also alphabet and numbers that end on P and 17… i maked this poor map fast, but now i explain it.
Region 1 - " Frozen sea" not from movies, but i thinked that those are north parts of map so there may be, frozen icebergs, seals, and other north stuff… thin ice, that u walk on it and may fall in if u are too heavy for it… sunken ships treasures … Titanic easter eggs… ( Many ideas are available on this )
P.S i readed about that, developers maked this area for dungeons, for that i maked region 3 but for that later when i get to that region.
Region 2 - " Vilayet Sea" : about this region, well name is because in original there should be sea between dafari and khitan, but because that map part is filled already, i used it on place where in old conan was eastern ocean… So about whats inside this region : whales, sharks, many small islands with hostile boss/treasures, some underwater dungeons also there would live those who are in “Agros” DLC… building sea bases and stuff ( also many ideas what can be there) + this part may be sailed with small ships or canoes… and on north side there may be continent - Actual “Lemuria” ( Region 4)
Region 3 - So now about Dungeon location , they may be setted there, because for conan that part is unreachable and with not reachable mountains, like in some dungeons “U cant climb this” then there will also add mountains on map and in real map… So nobody can reach it, on map it will be like snow mountains and instant death with warnings who are near - like ghosts who say that player will die or so, but in real,map full of dungeons, and there is many grids for them… just, no need to make it blank on “paper” map… just need to make unreachable… ( thats for dungeons)
Region 4 - Actual Lemuria : Lemuria is continent who sunked in oceans… There may be like swamp area with reptile atlantians or lemurians , ruins of Lemuria, and many other stuff ( also many ideas are placable there)
P.S I know devs said that map is done, but if they add DLC of lemurians and argos… its possible to make also map place for them… as for price, map can be added to original, but just price of game will be a bit higher…
p.S.S sorry for spelling mistakes. and i hope i writed it good… Such big suggestion is first time, and for conan its second suggestion for me… Thanks for ur time
