After you complete the Tutorial upon your first log-in, you will spawn in a busy area surrounded by a whole host of NPCs, players, sounds, and buildings. Arguably the most important building - and the one we will be focusing on right now - is just to the right of the Boros NPC near the walls of signs.
Alright, so you've walked into the building. Congrats, you're a big strong Lokan now! To meet up with your bigger, stronger Lokan friends in your Town, you'll need to walk into that white portal seen in the image above. Note that you'll have to be added to the Town first (ask your Town leaders to invite you, and accept the invite via chat)!
