The adventurer's guild checkpoint in Is Sahasi is located in the ruins of an old fortress, nestled deep in the mountains. The fortress walls are crumbling and overgrown with ivy, but the guild has managed to make the central courtyard a safe and secure area for adventurers to rest and resupply.
Upon entering the fortress, adventurers are greeted by a large stone archway adorned with the emblem of the guild. The archway leads to a wide-open courtyard that has been cleared of debris and outfitted with tents and other temporary structures to serve as the guild's checkpoint.
A large central tent serves as the guild's main office, where adventurers can register their quests and receive rewards for completed tasks. The tent is staffed by several guild officials who keep track of adventurers' progress and provide advice on upcoming quests.
Surrounding the central tent are a number of smaller tents and makeshift stalls, where local merchants and vendors sell goods and supplies to adventurers. The stalls offer everything from potions and enchanted gear to maps and guidebooks of the surrounding area.
The fortress walls are lined with watchtowers, where guards keep a lookout for any signs of danger in the surrounding mountains. The guild has also set up a training ground in one of the fortress's larger rooms, where adventurers can practice their combat skills and test out new gear.
