There is nothing special about this mid-sized town, but being situated directly south of the Privateer's Hold it should be a welcome sight for any adventurer who has just escaped the horrors of this place. Here, you can rest your weary head on a bed in the Fighters' Guild, sell your surplus weaponry and buy a wagon at a "rusty relics" general store, and buy your first spells at the Mages' Guild.
The Mages' Guild of Gothway Garden is of the second best variety ("better appointed than many"), spells you can buy here include Buoyancy (best spell for training just any scholl of magic), Stamina (good for training Restoration), Open and Sleep (needed for some Mages' Guild quests), Heal, and the indispensible Recall. And if you still have some cash left over after that, the Bank of Daggerfall will take care of it for you.
Ah yes, there is something special about Gothway Garden: It is probably the only not walled town with a bank.
