I've been to Lin a few times and it's not very exciting. It's a rough run from Nanto, full of nasty creatures. It's a little hilly town tucked into a forest, and the only road out again goes back to Nanto. It does have a portal to Khayyaban and Tou-to. Even the weapons and armor aren't that good, especially for an outpost town. Arrows are a whopping 175p! There's both a collector and a wing collector up the hill.

Lin main town: 54.7s, 73.1e
Lifestone: 55.6s, 74.1e
Khayyaban portal: 54.9s, 73.1e
Tou-to portal: 54.0s, 73.9e

Main fork between Lin, Nanto and Mayoi: 58.7, 79.1
