The first dungeon
You can visit the black citadel through lions arch, find the 5 portals near the middle (next to the Lion).
Then when you are in the citadel, go right and go to plains of ashford, keep going right and it’s in that map (you will find it, it’s about 3/4s of the map east).
1 – Will the plot eventually lead me there so I don’t have to worry about going all the way to Charr territory right now just to do this dungeon?
You should receive an in-game mail telling you about the dungeon. I can’t remember if they were tied to just hitting certain levels, or if it was dependant on getting to specific chapters of your storyline.
2 – Does everyone in your group needs to physically travel to the dungeon entrance or is there some sort of mechanic where someone can summon the rest of the party into the dungeon?
Everyone has to be on the same map, and in the same version of the map (in the case of overflows) for the prompt to come up when the “leader” enters the dungeon. You don’t have to specifically all be in front of the dungeon.
3 – Is it hard to find ppl to dungeon with? I don’t have a guild yet.
Guild is best, but there are PUG’s for it. There is no real “LFM” system like in other games. Groups outside of guild/friend runs are usually advertised in mapchat. The best non-guild runs I’ve seen will have a Vent or Mumble set up to facilitate communication, but these are not common.
I remember receiving this mail with a gate icon. I didn’t pay much attention to it but it’s still in my mail box, I’ll check it out.
Thank you guys.
