to access the city of yalahar you need to do some quests that will allow you to travel to the city. We will start with the explore society quest here you need to join the explorers guild I will post a spoiler if you want to see "
https://tibiawiki.com.br/wiki/The_Explorer_Society_Quest" but in short if you have money you can buy the dwarven pickaxe at market and deliver to one of the npcs of explore at once I advise you to go to Angus (right from the port hope dp) is the closest. There you can give hi-join-yes-yes-dwarven pickaxe-yes >> buying the item on the market saves you 30m + - of quest. The pickaxe dwarven costs an average of 5-10k. If you have money I would advise you to buy all the items to do the second part after having access to make your life easier travel to venore and buy a Sample of Venorean Spice (200gps) at Rodney's store (fruit store), then travel to darashia and at the fair north of dp talk to Omur and buy him a Sample of Sand Wasp Honey (200gps), then go to ankrahmun and north of dp where you sell portions buy a Jug of Embalming Fluid from Mehkesh (200gps), after go to liberty bay and in the tavern to the left of the dp buy a Lyonel Rum Flask (150gps) and lastly go to carlin and near the temple at the florist shop buy a Bowl of Evergreen Flowers (150gps) from Florentine. With all these items already in hand, travel to Edron this time and head to the Noodles Academy of Modern Magic (where you buy portions and spells - southeast of the dp) there you need to talk to Wyrdin to start the "The Way to Yalahar Quest". That done he tells you to go to Yalahar, for that you will have to use a different route going to liberty bay and on the pier on the right side look for Captain Max he will take you to Yalahar. Once there you will go up to the mast of the naval next to which you disembarked and will speak to an Elf named Karith speaking hi-passage-venore, ankrahmun-darashia-liberty bay-carlin. With that done you will now have the right to travel by almost all the boats from tibia straight to yalahar without having to go every time to liberty bay traveling with the Capitan Marx this will save you money and time. To finish the quest at once look for Timothy he is north of the DP and talk about the research notes. Now just go to edron's gym again and give it to Wyrdin and be happy xD
